# Section 06 - Bug Catching Contest and Sudowoodo
Source: `../section-06-bug-catching-contest-and-sudowoodo.txt`
Maps covered: `MAP_GOLDENROD_FLOWER_SHOP`, `MAP_ROUTE_35_GOLDENROD_GATE`, `MAP_ROUTE_35`,
`MAP_ROUTE_35_NATIONAL_PARK_GATE`, `MAP_NATIONAL_PARK`, `MAP_NATIONAL_PARK_BUG_CONTEST`,
`MAP_ROUTE_36_NATIONAL_PARK_GATE`, `MAP_ROUTE_36`, `MAP_ROUTE_37` (listed by the
walkthrough header, never entered by its route)
Badges / key milestones in this section:
- SQUIRTBOTTLE (key item) - gated behind `ENGINE_PLAINBADGE`, i.e. Whitney must already
be beaten before this section can be started at all.
- Bug-Catching Contest run (Tue/Thu/Sat only) - SUN STONE / EVERSTONE / GOLD BERRY / BERRY.
- `EVENT_FOUGHT_SUDOWOODO` - the single event that unblocks Route 36 west<->east, which
is the only land route between Goldenrod and Violet through Route 36.
- TM08 ROCK SMASH (`EVENT_GOT_TM08_ROCK_SMASH`), TM04 ROLLOUT, TM28 DIG, QUICK CLAW.
- No badge is earned in this section.
Everything in this file was transcribed from files that were opened; nothing is

## 1. Route order
The walkthrough's own prose is out of order in one place: it opens by collecting the
SQUIRTBOTTLE in Goldenrod, then much later describes Floria running off to fetch it.
In pokegold the SQUIRTBOTTLE has no Route 36 precondition at all (see
"Unresolved / verify by hand"), so the opening order is the one a bot should follow.
| # | Map constant | asm file | Enter via | Leaves via | Why (walkthrough beat) |
|---|---|---|---|---|---|
| 1 | `MAP_GOLDENROD_FLOWER_SHOP` | `maps/GoldenrodFlowerShop.asm` | `GOLDENROD_CITY` warp 6 @ (33, 5) | warp 1/2 @ (2,7)/(3,7) -> `GOLDENROD_CITY` 6 | Talk to the teacher for the SQUIRTBOTTLE |
| 2 | `MAP_ROUTE_35_GOLDENROD_GATE` | `maps/Route35GoldenrodGate.asm` | `GOLDENROD_CITY` warp 13 @ (19, 1) -> gate warp 3 | warp 1/2 @ (4,0)/(5,0) -> `ROUTE_35` 1/2 | Randy hands over Kenya the SPEAROW with FLOWER MAIL |
| 3 | `MAP_ROUTE_35` | `maps/Route35.asm` | gate warp @ (9,33)/(10,33) | warp 3 @ (3, 5) -> `ROUTE_35_NATIONAL_PARK_GATE` 3 | Six trainers + Officer Dirk, walk north |
| 4 | `MAP_ROUTE_35_NATIONAL_PARK_GATE` | `maps/Route35NationalParkGate.asm` | warp 3/4 @ (3,7)/(4,7) | warp 1/2 @ (3,0)/(4,0) -> `NATIONAL_PARK` 3/4 | Contest officer; optional entry to the Contest |
| 5 | `MAP_NATIONAL_PARK_BUG_CONTEST` | `maps/NationalParkBugContest.asm` | script `warp NATIONAL_PARK_BUG_CONTEST, 10, 47` from the south gate (or `33, 18` from the north gate) | contest timer / balls exhausted, or either gate | Optional Tue/Thu/Sat Contest |
| 6 | `MAP_NATIONAL_PARK` | `maps/NationalPark.asm` | warp 3/4 @ (10,47)/(11,47) | warp 1/2 @ (33,18)/(33,19) -> `ROUTE_36_NATIONAL_PARK_GATE` 1/2 | QUICK CLAW, Beverly, Jack, Krise, William, TM28 DIG |
| 7 | `MAP_ROUTE_36_NATIONAL_PARK_GATE` | `maps/Route36NationalParkGate.asm` | warp 1/2 @ (0,4)/(0,5) | warp 3/4 @ (9,4)/(9,5) -> `ROUTE_36` 1/2 | Contest results / prize holding |
| 8 | `MAP_ROUTE_36` | `maps/Route36.asm` | warp 1/2 @ (18,8)/(18,9) | south connection @ y=17 -> `ROUTE_35`; later east connection -> `VIOLET_CITY` | Ice Berry, Psychic Mark, Schoolboy Alan, Sudowoodo, TM08 |
| 9 | `MAP_ROUTE_35` (again) | `maps/Route35.asm` | north connection from `ROUTE_36` (offset 0) | back north to `ROUTE_36` | Cut the tree, Bug Catcher Arnie, Bird Keeper Bryan, TM04 ROLLOUT |
| 10 | `MAP_ROUTE_36` (again) | `maps/Route36.asm` | north connection from `ROUTE_35` | **east connection -> `VIOLET_CITY`** | Sudowoodo cleared, then east into Violet City |
Spills into the next section: step 10's east connection
(`connection east, VioletCity, VIOLET_CITY, 0` in `data/maps/attributes.asm`) drops the
player into `MAP_VIOLET_CITY`, which belongs to a neighbouring section. Route 37
(`MAP_ROUTE_37`, north connection off Route 36 with offset 10) is named in this section's
header but the walkthrough never routes into it; its data is recorded below for
completeness because the item list ("Blk/Blu/Red Apricorn", "Ice Berry") mixes 36 and 37.

## 2. Maps
### MAP_GOLDENROD_FLOWER_SHOP
- Script: `maps/GoldenrodFlowerShop.asm`
- Blocks: `maps/GoldenrodFlowerShop.blk`
- Header (`data/maps/maps.asm:275`): `TILESET_HOUSE, INDOOR, LANDMARK_GOLDENROD_CITY, MUSIC_GOLDENROD_CITY, FALSE, PALETTE_DAY, FISHGROUP_SHORE`
- Dimensions: `constants/map_constants.asm:253` -> `map_const GOLDENROD_FLOWER_SHOP, 4, 4`
- Connections: none (indoor)
**Warps** (`def_warp_events`)
| idx | x | y | destination map | dest warp |
|---|---|---|---|---|
| 1 | 2 | 7 | `GOLDENROD_CITY` | 6 |
| 2 | 3 | 7 | `GOLDENROD_CITY` | 6 |
**Coord events** (`def_coord_events`) - none.
**BG events** (`def_bg_events`) - none. (`FlowerShopShelf1`, `FlowerShopShelf2`,
`FlowerShopRadio` exist in the file but are marked `; unreferenced`.)
**Object events** (`def_object_events`)
| const | sprite | x | y | movement | type | script label | event flag |
|---|---|---|---|---|---|---|---|
| `GOLDENRODFLOWERSHOP_TEACHER` | `SPRITE_TEACHER` | 2 | 4 | `SPRITEMOVEDATA_STANDING_RIGHT` | `OBJECTTYPE_SCRIPT` | `FlowerShopTeacherScript` | -1 |
| `GOLDENRODFLOWERSHOP_FLORIA` | `SPRITE_LASS` | 5 | 6 | `SPRITEMOVEDATA_WANDER` (1,1) | `OBJECTTYPE_SCRIPT` | `FlowerShopFloriaScript` | -1 |
**Scripts of interest**
- `FlowerShopTeacherScript` (`57:52d1`) - `checkevent EVENT_GOT_SQUIRTBOTTLE` /
`iftrue .Lalala`; then `checkflag ENGINE_PLAINBADGE` / `iffalse .Lalala`. Only with the
badge and without the event does it `faceplayer` / `opentext` /
`writetext GoldenrodFlowerShopTeacherBetterThanWhitneyText` / `promptbutton` /
`verbosegiveitem SQUIRTBOTTLE` / `setevent EVENT_GOT_SQUIRTBOTTLE`. **Note the bug in
the cart**: there is no `iffalse` after `verbosegiveitem`, so a full PACK still sets
`EVENT_GOT_SQUIRTBOTTLE` and the item is lost. A bot must have a free KEY ITEM slot.
- `FlowerShopFloriaScript` (`57:52f4`) - pure flavour, branches on `ENGINE_PLAINBADGE`.
Gives nothing.
**Flags and events**
| constant | defined in | read/written by | meaning for a bot |
|---|---|---|---|
| `EVENT_GOT_SQUIRTBOTTLE` | `constants/event_flags.asm:101` | read+written by `FlowerShopTeacherScript` | one-shot; set even on a full bag |
| `ENGINE_PLAINBADGE` | `constants/engine_flags.asm:40` | read by `FlowerShopTeacherScript`, `FlowerShopFloriaScript` | Whitney's badge is the hard precondition for the whole section |
**Items**
| item | how obtained | source (label / bg_event / hidden) | one-time flag |
|---|---|---|---|
| `SQUIRTBOTTLE` | talk to teacher at (2,4) | `FlowerShopTeacherScript` `verbosegiveitem` | `EVENT_GOT_SQUIRTBOTTLE` |
**Trainers** - none.
**Wild encounters** - none (indoor).
---
### MAP_ROUTE_35_GOLDENROD_GATE
- Script: `maps/Route35GoldenrodGate.asm`
- Blocks: no `.blk` in `maps/` for this map (gate maps of this group share generated
attributes; `data/maps/attributes.asm:542` carries `map_attributes Route35GoldenrodGate, ROUTE_35_GOLDENROD_GATE, $00`)
- Header (`data/maps/maps.asm:260`): `TILESET_GATE, GATE, LANDMARK_ROUTE_35, MUSIC_ROUTE_36, FALSE, PALETTE_DAY, FISHGROUP_SHORE`
- Dimensions: `constants/map_constants.asm:239` -> `map_const ROUTE_35_GOLDENROD_GATE, 5, 4`
- Connections: none. `GATE` environment is why the walkthrough's "ride your bike through"
works.
**Warps** (`def_warp_events`)
| idx | x | y | destination map | dest warp |
|---|---|---|---|---|
| 1 | 4 | 0 | `ROUTE_35` | 1 |
| 2 | 5 | 0 | `ROUTE_35` | 2 |
| 3 | 4 | 7 | `GOLDENROD_CITY` | 13 |
| 4 | 5 | 7 | `GOLDENROD_CITY` | 13 |
**Coord events** - none. **BG events** - none.
**Object events**
| const | sprite | x | y | movement | type | script label | event flag |
|---|---|---|---|---|---|---|---|
| `ROUTE35GOLDENRODGATE_RANDY` | `SPRITE_OFFICER` | 0 | 4 | `SPRITEMOVEDATA_STANDING_RIGHT` | `OBJECTTYPE_SCRIPT` | `RandyScript` | -1 |
| `ROUTE35GOLDENRODGATE_POKEFAN_F` | `SPRITE_POKEFAN_F` | 6 | 4 | `SPRITEMOVEDATA_WALK_UP_DOWN` (0,1) | `OBJECTTYPE_SCRIPT` | `Route35GoldenrodGatePokefanFScript` | -1 |
**Scripts of interest**
- `RandyScript` (`56:59ce`) - four-way branch, checked in this order:
`EVENT_GOT_HP_UP_FROM_RANDY` -> `.gothpup`; `EVENT_GAVE_KENYA` -> `.questcomplete`
(`verbosegiveitem HP_UP`, `setevent EVENT_GOT_HP_UP_FROM_RANDY`);
`EVENT_GOT_KENYA` -> `.alreadyhavekenya`; otherwise the offer. On YES it prints thanks,
then `readvar VAR_PARTYCOUNT` / `ifequal PARTY_LENGTH, .partyfull`. Only with a free
slot does it run `givepoke SPEAROW, 10, NO_ITEM, GiftSpearowName, GiftSpearowOTName`,
`givepokemail GiftSpearowMail`, `setevent EVENT_GOT_KENYA`.
- `GiftSpearowMail` = `FLOWER_MAIL`, text `"DARK CAVE leads / to another road"`.
- `GiftSpearowName` = `KENYA`, `GiftSpearowOTName` = `RANDY`.
- The delivery target (`EVENT_GAVE_KENYA`) is on Route 31, i.e. a later section.
- `Route35GoldenrodGatePokefanFScript` - flavour, branches on `EVENT_FOUGHT_SUDOWOODO`;
its pre-Sudowoodo text is the in-game hint that the SQUIRTBOTTLE is what wakes the tree.
**Flags and events**
| constant | defined in | read/written by | meaning for a bot |
|---|---|---|---|
| `EVENT_GOT_KENYA` | `constants/event_flags.asm:89` | `RandyScript` | Spearow accepted |
| `EVENT_GAVE_KENYA` | `constants/event_flags.asm:90` | read here, set on Route 31 | enables the HP UP reward |
| `EVENT_GOT_HP_UP_FROM_RANDY` | `constants/event_flags.asm:91` | `RandyScript` | reward taken |
| `EVENT_FOUGHT_SUDOWOODO` | `constants/event_flags.asm:51` | read here | flavour only on this map |
**Items**
| item | how obtained | source | one-time flag |
|---|---|---|---|
| SPEAROW "KENYA" (lv 10) + `FLOWER_MAIL` | say YES to Randy with a party slot free | `RandyScript` `givepoke` / `givepokemail` | `EVENT_GOT_KENYA` |
| `HP_UP` | return after delivering to Route 31 | `RandyScript` `.questcomplete` | `EVENT_GOT_HP_UP_FROM_RANDY` |
**Trainers** - none. **Wild encounters** - none.

### MAP_ROUTE_35
- Script: `maps/Route35.asm`
- Blocks: `maps/Route35.blk` (180 bytes = 10 x 18 blocks)
- Header (`data/maps/maps.asm:248`): `TILESET_JOHTO, ROUTE, LANDMARK_ROUTE_35, MUSIC_ROUTE_36, FALSE, PALETTE_AUTO, FISHGROUP_POND`
- Dimensions: `constants/map_constants.asm:227` -> `map_const ROUTE_35, 10, 18` (so cell
coordinates run 0..19 in x and 0..35 in y)
- Connections (`data/maps/attributes.asm:202`): north `ROUTE_36` offset 0, south
`GOLDENROD_CITY` offset -5
**Warps** (`def_warp_events`)
| idx | x | y | destination map | dest warp |
|---|---|---|---|---|
| 1 | 9 | 33 | `ROUTE_35_GOLDENROD_GATE` | 1 |
| 2 | 10 | 33 | `ROUTE_35_GOLDENROD_GATE` | 2 |
| 3 | 3 | 5 | `ROUTE_35_NATIONAL_PARK_GATE` | 3 |
**Coord events** - none.
**BG events** (`def_bg_events`)
| x | y | type | script/item |
|---|---|---|---|
| 1 | 7 | `BGEVENT_READ` | `Route35Sign` |
| 11 | 31 | `BGEVENT_READ` | `Route35Sign` |
**Object events** (`def_object_events`)

| `ROUTE35_POKE_BALL` | `SPRITE_POKE_BALL` | 13 | 16 | `STILL` | `OBJECTTYPE_ITEMBALL` | `Route35TMRollout` (`4b:5c05`) | `EVENT_ROUTE_35_TM_ROLLOUT` |
**Scripts of interest**
- `TrainerOfficerDirk` - **not** an `OBJECTTYPE_TRAINER` object. It is a plain script that
runs `checktime NITE` / `iffalse .NotNight` first, so Dirk only battles at night. Then
`checkevent EVENT_BEAT_OFFICER_DIRK`, `playmusic MUSIC_OFFICER_ENCOUNTER`,
`winlosstext OfficerDirkBeatenText, 0`, `loadtrainer OFFICER, DIRK`, `startbattle`,
`reloadmapafterbattle`, `setevent EVENT_BEAT_OFFICER_DIRK`. A daytime bot will get
`OfficerDirkPrettyToughText` and no battle.
- `TrainerJugglerIrwin` / `TrainerBugCatcherArnie` - standard phone trainers. After the
win, `checkcellnum PHONE_JUGGLER_IRWIN` / `PHONE_BUG_CATCHER_ARNIE`, then
`setevent EVENT_IRWIN_ASKED_FOR_PHONE_NUMBER` / `EVENT_ARNIE_ASKED_FOR_PHONE_NUMBER`
and `askforphonenumber`. The walkthrough's "head back to Arnie and talk to her for her
phone number" is this second talk.
Rematch tiers: Irwin uses `EVENT_CLEARED_RADIO_TOWER` -> `IRWIN3`,
`ENGINE_FLYPOINT_CIANWOOD` -> `IRWIN2`, else `IRWIN1`. Arnie uses
`ENGINE_FLYPOINT_BLACKTHORN` -> `ARNIE3`, `ENGINE_FLYPOINT_LAKE_OF_RAGE` -> `ARNIE2`,
else `ARNIE1`.
- `Route35TMRollout` -> `itemball TM_ROLLOUT`. `Route35FruitTree` -> `fruittree FRUITTREE_ROUTE_35`.
**Flags and events**
| constant | defined in | read/written by | meaning for a bot |
|---|---|---|---|
| `EVENT_BEAT_PICNICKER_KIM` / `_CAMPER_ELLIOT` / `_PICNICKER_BROOKE` / `_CAMPER_IVAN` / `_JUGGLER_IRWIN` / `_FIREBREATHER_WALT` / `_BUG_CATCHER_ARNIE` / `_BIRD_KEEPER_BRYAN` | `constants/event_flags.asm` | `trainer` macro rows | per-trainer defeated bits |
| `EVENT_BEAT_OFFICER_DIRK` | `constants/event_flags.asm` | `TrainerOfficerDirk` | set by hand, not by the `trainer` macro |
| `EVENT_ROUTE_35_TM_ROLLOUT` | `constants/event_flags.asm:1107` | item ball object | TM04 taken |
| `EVENT_IRWIN_ASKED_FOR_PHONE_NUMBER`, `EVENT_IRWIN_READY_FOR_REMATCH` | `constants/event_flags.asm` | Irwin script | phone state machine |
| `EVENT_ARNIE_ASKED_FOR_PHONE_NUMBER`, `EVENT_ARNIE_READY_FOR_REMATCH` | `constants/event_flags.asm` | Arnie script | phone state machine |
**Items**
| item | how obtained | source | one-time flag |
|---|---|---|---|
| `TM_ROLLOUT` (TM04, `constants/item_constants.asm:223`) | item ball at cell (13, 16) | `Route35TMRollout` | `EVENT_ROUTE_35_TM_ROLLOUT` |
| `MYSTERYBERRY` | fruit tree object at (2, 25) | `FRUITTREE_ROUTE_35` -> `data/items/fruit_trees.asm:14` | daily reset (`Apricorns`/`TryResetFruitTrees` equivalent) |
**Trainers**
| const | class | id | party (`data/trainers/parties.asm` label) | script label | rematch/phone |

| `DIRK` | `OFFICER` (0x41) | 2 | `parties.asm:3172` `DIRK` - lv14 GROWLITHE, lv14 GROWLITHE | `TrainerOfficerDirk` | night only |
| `ARNIE1` | `BUG_CATCHER` (0x24) | 8 | `parties.asm:1455` `ARNIE` - lv15 VENONAT | `TrainerBugCatcherArnie` | yes (`PHONE_BUG_CATCHER_ARNIE`); ARNIE2 `parties.asm:1487`, ARNIE3 `parties.asm:1492` (lv28 VENOMOTH w/ moves) |
| `BRYAN` | `BIRD_KEEPER` (0x18) | 3 | `parties.asm:534` `BRYAN` - lv12 PIDGEY, lv14 PIDGEOTTO | `TrainerBirdKeeperBryan` | no |
**Wild encounters** - `data/wild/johto_grass.asm`, `def_grass_wildmons ROUTE_35`,
rates 10/10/10 percent (morn/day/nite). Gold table:
| slot | morn | day | nite |
|---|---|---|---|
| 1 | 12 NIDORAN_M | 12 NIDORAN_M | 12 NIDORAN_M |
| 2 | 12 NIDORAN_F | 12 NIDORAN_F | 12 NIDORAN_F |
| 3 | 14 DROWZEE | 14 DROWZEE | 14 DROWZEE |
| 4 | 10 ABRA | 10 ABRA | 10 ABRA |
| 5 | 14 PIDGEY | 14 PIDGEY | 14 HOOTHOOT |
| 6 | 10 DITTO | 10 DITTO | 10 DITTO |
| 7 | 12 YANMA | 12 YANMA | 12 YANMA |
(Silver swaps slots 1/2 to NIDORAN_F/NIDORAN_M.)
Water (`data/wild/johto_water.asm:156` `def_water_wildmons ROUTE_35`): 4 percent -
20 PSYDUCK, 15 PSYDUCK, 20 GOLDUCK. Fishing group is `FISHGROUP_POND`
(`data/wild/fish.asm:15`). Headbutt: `data/wild/treemon_maps.asm:16` ->
`TREEMON_SET_FOREST` (`data/wild/treemons.asm:34`; Gold common CATERPIE/METAPOD/
EXEGGCUTE/BUTTERFREE, rare adds PINECO). Swarm: `data/wild/swarm_grass.asm:6` is the
YANMA swarm table for `ROUTE_35`.
**Cut tree** - `maps/Route35.blk` has exactly one cuttable block: block id `$5b` at block
(8, 3), i.e. walk cells x 16-17, y 6-7. `data/collision/field_move_blocks.asm:14` gives
`db $5b, $3c, 0` for `TILESET_JOHTO`. That is the tree the walkthrough tells the player to
cut, and Bug Catcher Arnie at (16, 7) sits immediately behind it. Route 36, Route 37 and
National Park have **no** cuttable blocks (National Park's `.park` entry in
`field_move_blocks.asm` is only the two grass ids `$13` and `$03`).

Paras, Venonat, Butterfree, Beedrill) are **Contest-only**; see below.

### MAP_NATIONAL_PARK_BUG_CONTEST
- Script: `maps/NationalParkBugContest.asm`
- Blocks: none of its own; `data/maps/attributes.asm:413` gives
`map_attributes NationalParkBugContest, NATIONAL_PARK_BUG_CONTEST, $00` and the map is a
same-geometry twin of National Park.
- Header (`data/maps/maps.asm:94`): `TILESET_PARK, ROUTE, LANDMARK_NATIONAL_PARK, MUSIC_BUG_CATCHING_CONTEST, FALSE, PALETTE_AUTO, FISHGROUP_SHORE`

(Warps 2 and 4 point at dest warp 1, not 2 - that is what the file says.)
**Coord events** - none.
**BG events** - same four rows as National Park, aimed at the `...BugContest...` copies:
(14,44) Relaxation Square sign, (27,31) Battle Notice sign, (6,47) `BGEVENT_ITEM`
`hiddenitem FULL_HEAL, EVENT_NATIONAL_PARK_HIDDEN_FULL_HEAL` (the same flag as the normal

**Scripts of interest**
- Every `BugCatchingContestantNAScript` is `faceplayer / opentext / writetext / waitbutton
/ closetext / end` - flavour only, no branching. The `B` variants in the north gate are
the ones that branch on `EVENT_TEMPORARY_UNTIL_MAP_RELOAD_1` (set by
`BugContestResults_FirstPlace`) to say "you won".
- The battle path is `BugCatchingContestBattleScript::`
(`engine/events/bug_contest/contest.asm:9`): `loadvar VAR_BATTLETYPE, BATTLETYPE_CONTEST`,
`randomwildmon`, `startbattle`, `reloadmapafterbattle`, `readmem wParkBallsRemaining`,
`iffalse BugCatchingContestOutOfBallsScript`.
- `GiveParkBalls` (`engine/events/bug_contest/contest.asm:1`) clears `wContestMon`, writes
`BUG_CONTEST_BALLS` into `wParkBallsRemaining` and `farcall StartBugContestTimer`.
**Contest constants** (`constants/script_constants.asm`)
| constant | line | value |
|---|---|---|
| `BUG_CONTEST_BALLS` | 283 | 20 |
| `BUG_CONTEST_MINUTES` | 284 | 20 |
| `BUG_CONTEST_PLAYER` | 286 | 1 |
| `NUM_BUG_CONTESTANTS` | 287 | 10 (not counting the player) |
| `VAR_CONTESTMINUTES` | 65 | var id 0x11 |
**Contest wild table** - `data/wild/bug_contest_mons.asm`, label `ContestMons`
(`25:7bb8`). This table replaces National Park's grass entirely for the duration:
| % | species | min lv | max lv |
|---|---|---|---|
| 20 | CATERPIE | 7 | 18 |
| 20 | WEEDLE | 7 | 18 |
| 10 | METAPOD | 9 | 18 |

| 10 | PARAS | 10 | 17 |
| 5 | SCYTHER | 13 | 14 |
| 5 | PINSIR | 13 | 14 |
| -1 (terminator row) | VENOMOTH | 30 | 40 |
**Scoring** - `ContestScore` (`04:7cbc`, `engine/events/bug_contest/judging.asm`) sums:
`MaxHP * 4` (high byte only), then Attack, Defense, Speed, SpclAtk, SpclDef, then a DV
bonus assembled from bit 1 of each DV nibble, then `remaining HP / 8`, then `+1` if the
mon is holding an item. Five of the ten AI contestants are rolled by
`ComputeAIContestantScores`, each picking one of three canned mon/score pairs from
`BugContestantPointers` (`data/events/bug_contest_winners.asm`) with a 0..7 random
perturbation. `DetermineContestWinners` keeps a 3-deep podium.
**Prizes** - `BugContestResultsScript` (`40:420e`, `engine/events/std_scripts.asm:275`):
| place | item | no-room fallback flag |
|---|---|---|
| 1st | `SUN_STONE` | `EVENT_CONTEST_OFFICER_HAS_SUN_STONE` |
| 2nd | `EVERSTONE` | `EVENT_CONTEST_OFFICER_HAS_EVERSTONE` |
| 3rd | `GOLD_BERRY` | `EVENT_CONTEST_OFFICER_HAS_GOLD_BERRY` |
| consolation | `BERRY` | `EVENT_CONTEST_OFFICER_HAS_BERRY` |
First place also sets `EVENT_TEMPORARY_UNTIL_MAP_RELOAD_1`. The tail of the script clears
`ENGINE_BUG_CONTEST_TIMER`, sets all twenty `EVENT_BUG_CATCHING_CONTESTANT_*` flags, sets
`ENGINE_DAILY_BUG_CONTEST`, and resets both gate scenes to their NOOP.

(`56:6710`): first `checkevent EVENT_WARPED_FROM_ROUTE_35_NATIONAL_PARK_GATE` -> return
unchanged (this is how the awards ceremony keeps the contest officer standing there when
you finished from the *south* gate). Then weekday / `ENGINE_BUG_CONTEST_TIMER`, same as
the south gate.
**Scripts of interest**
- `Route36OfficerScriptContest` (`56:67cc`) - same structure as the south gate's officer
but warps to `NATIONAL_PARK_BUG_CONTEST, 33, 18` and, if `ENGINE_DAILY_BUG_CONTEST` is
already set, falls into `Route36Officer_ContestHasConcluded`, which is the **prize
holding desk**: it checks `EVENT_CONTEST_OFFICER_HAS_SUN_STONE`, then `_EVERSTONE`, then
`_GOLD_BERRY`, then `_BERRY`, `verbosegiveitem`s the first one it finds and clears that
event. A bot that won with a full PACK collects here.
- `Route36NationalParkGateLeavingContestEarlyScript` - the finish-now flow.
`special FadeOutToBlack`, `.CopyContestants` (turns each unset `..._NA` flag into an
`appear` of the matching `B` object), `disappear OFFICER1` / `appear OFFICER2`,
`applymovement PLAYER, Route36NationalParkGatePlayerWaitWithContestantsMovement`
(`big_step DOWN`, `big_step RIGHT`, `turn_head UP`), then
`jumpstd BugContestResultsScript`.

**Callbacks**
- `MAPCALLBACK_OBJECTS` -> `Route36ArthurCallback` (`4b:619e`): `readvar VAR_WEEKDAY`,
`ifequal THURSDAY, .ArthurAppears` (-> `appear ROUTE36_ARTHUR`), otherwise
`disappear ROUTE36_ARTHUR`.
**Scripts of interest**
- `SudowoodoScript` (`4b:61aa`) - the gate of this section.
`checkitem SQUIRTBOTTLE` / `iftrue .Fight`. Without it: `waitsfx`,
`playsound SFX_SANDSTORM`, `applymovement ROUTE36_WEIRD_TREE, SudowoodoShakeMovement`
(`tree_shake`), `end` - the tree just wobbles and stays solid.
With it: `writetext UseSquirtbottleText`, `yesorno`, `iffalse DidntUseSquirtbottleScript`.
- `WateredWeirdTreeScript::` (`4b:61c1`) - exported so that using the SQUIRTBOTTLE from the
PACK reaches the same body (`engine/events/squirtbottle.asm` does
`farsjump WateredWeirdTreeScript`). Body: text, shake, `SudowoodoAttackedText`,
**`loadwildmon SUDOWOODO, 20`**, `startbattle`, `setevent EVENT_FOUGHT_SUDOWOODO`,
`ifequal DRAW, DidntCatchSudowoodo`, `disappear ROUTE36_WEIRD_TREE`,
`variablesprite SPRITE_WEIRD_TREE, SPRITE_TWIN`, `reloadmapafterbattle`.
Note the ordering: `EVENT_FOUGHT_SUDOWOODO` is set **before** the DRAW check, so a run
or a KO still clears the road and still unlocks TM08.
- `DidntCatchSudowoodo` (`4b:61e9`) - `reloadmapafterbattle`,
`applymovement ROUTE36_WEIRD_TREE, WeirdTreeMovement_Flee` (two `fast_jump_step UP`),
`disappear`, `variablesprite`, `special LoadUsedSpritesGFX`.
- `_Squirtbottle` (`14:4763`, `engine/events/squirtbottle.asm`) - the PACK path.
`.CheckCanUseSquirtbottle` requires `wMapGroup == GROUP_ROUTE_36`,
`wMapNumber == MAP_ROUTE_36`, `GetFacingObject` to succeed, and that object's movement
data to be `SPRITEMOVEDATA_SUDOWOODO`. Anything else prints
`_SquirtbottleNothingText`.
- `Route36RockSmashGuyScript` (`4b:61f7`) - `checkevent EVENT_GOT_TM08_ROCK_SMASH` ->
`.AlreadyGotRockSmash`; `checkevent EVENT_FOUGHT_SUDOWOODO` -> `.ClearedSudowoodo`
(`verbosegiveitem TM_ROCK_SMASH`, `iffalse .NoRoomForTM`,
`setevent EVENT_GOT_TM08_ROCK_SMASH`). Before Sudowoodo it just prints
`RockSmashGuyText1`.
- `ArthurScript` (`4b:62d4`) - `checkevent EVENT_GOT_HARD_STONE_FROM_ARTHUR` ->
`.AlreadyGotStone`; `readvar VAR_WEEKDAY` / `ifnotequal THURSDAY, ArthurNotThursdayScript`;
else `setevent EVENT_MET_ARTHUR_OF_THURSDAY`, `verbosegiveitem HARD_STONE`,
`iffalse .BagFull`, `setevent EVENT_GOT_HARD_STONE_FROM_ARTHUR`.
- `Route36LassScript` (`4b:621e`) - flavour, branches on `EVENT_FOUGHT_SUDOWOODO`. This is
the girl at (51, 8). She is **not** Floria and gives nothing.

## 3. Blockers and gates
| Gate | Enforced by (file:label) | Requirement | Unlock condition |
|---|---|---|---|
| SQUIRTBOTTLE not obtainable | `maps/GoldenrodFlowerShop.asm:FlowerShopTeacherScript` (`57:52d1`) - `checkflag ENGINE_PLAINBADGE` / `iffalse .Lalala` | Plain Badge (Whitney) | beat Whitney; talk to the teacher at (2,4) |
| Sudowoodo blocks Route 36 | `maps/Route36.asm:SudowoodoScript` (`4b:61aa`) - the object at cell (35,9) with `SPRITEMOVEDATA_SUDOWOODO` is a solid NPC; the script's `checkitem SQUIRTBOTTLE` / `iftrue .Fight` is the only way past | SQUIRTBOTTLE in the PACK | `EVENT_FOUGHT_SUDOWOODO` set by `WateredWeirdTreeScript` (`4b:61c1`); the `disappear` runs on any outcome except a draw-flee, and the flee path disappears it too |
| SQUIRTBOTTLE from the PACK does nothing elsewhere | `engine/events/squirtbottle.asm:_Squirtbottle` (`14:4763`) `.CheckCanUseSquirtbottle` | map must be `ROUTE_36` and the faced object must carry `SPRITEMOVEDATA_SUDOWOODO` | face the tree first |
| TM08 ROCK SMASH withheld | `maps/Route36.asm:Route36RockSmashGuyScript` (`4b:61f7`) - `checkevent EVENT_FOUGHT_SUDOWOODO` | Sudowoodo dealt with | talk to the fisher at (44, 9) |
| East side of Route 35 (Arnie, Bryan, TM04) | `maps/Route35.blk` block `$5b` at block (8,3) = cells x16-17 y6-7; `data/collision/field_move_blocks.asm:14` | CUT, which needs `ENGINE_HIVEBADGE` (`engine/events/overworld.asm:133` `CutFunction.CheckAble`) and a party mon that knows CUT | Azalea's badge + HM01; or enter from Route 36 via the south connection, which is what the walkthrough does |
| Bug Contest closed | `maps/Route35NationalParkGate.asm:Route35OfficerScriptContest` (`56:5e0c`) and `maps/Route36NationalParkGate.asm:Route36OfficerScriptContest` (`56:67cc`) - `readvar VAR_WEEKDAY`, four `ifequal` bail-outs, plus `checkflag ENGINE_DAILY_BUG_CONTEST` | Tuesday, Thursday or Saturday, and not already run today | set the RTC weekday; `ENGINE_DAILY_BUG_CONTEST` clears on the daily reset |
| Contest entry refused | same scripts - `readvar VAR_PARTYCOUNT` / `VAR_BOXSPACE` / `special CheckFirstMonIsEgg` / `special ContestDropOffMons` | lead mon is not an EGG, is not fainted, and there is party-or-box room for a caught bug | reorder the party, heal, free a box slot |
| Kenya not given | `maps/Route35GoldenrodGate.asm:RandyScript` (`56:59ce`) - `readvar VAR_PARTYCOUNT` / `ifequal PARTY_LENGTH, .partyfull` | fewer than 6 party mons | deposit one |
| Arthur / Sunny absent | `Route36ArthurCallback` (`4b:619e`) / `Route37SunnyCallback` - `MAPCALLBACK_OBJECTS` + `VAR_WEEKDAY` | Thursday / Sunday | RTC weekday |
| Officer Dirk will not battle | `maps/Route35.asm:TrainerOfficerDirk` - `checktime NITE` / `iffalse .NotNight` | night time of day | wait, or set the RTC |

## 5. Port coverage
| Beat | Port file | Status |
|---|---|---|
| Map geometry, warps, bg/object events for all nine maps | `src/import/RomExtractorGen2.lua` (extracted into the cache), consumed by `src/world/gen2/World.lua` / `Map.lua` | implemented (data-driven; nothing map-specific is hand written) |
| Script bytecode for every label above (`FlowerShopTeacherScript`, `RandyScript`, `SudowoodoScript`, `Route36RockSmashGuyScript`, `ArthurScript`, both contest officers, `BugContestResultsScript`) | `src/script/gen2/Vm.lua` + extracted bytecode | implemented - the opcodes these scripts use (`checkevent`, `checkflag`, `checkitem`, `verbosegiveitem`, `givepoke`, `givepokemail`, `loadwildmon`, `variablesprite`, `appear`/`disappear`, `setscene`, `sdefer`, `askforphonenumber`, `checkcellnum`, `checktime`, `fruittree`) all have branches in `Vm.lua` / `Opcodes.lua` |
| `VAR_WEEKDAY` (Arthur, Sunny, contest days) | `src/world/gen2/World.lua:1201` `World:weekday`, `World.lua:101` `VAR_WEEKDAY = 0x0b` | implemented |
| `MAPCALLBACK_OBJECTS` day-of-week NPC swaps | `src/world/gen2/World.lua:5991` `World:runMapCallback`, called from `World.lua:5700` | implemented; assertion driver `tests/drivers/gold_map_callbacks.lua` exists but does **not** cover Route 36 / Route 37 / either park gate |
| Bug Catching Contest rules, timer, park balls, scoring, AI contestants, prizes | `src/core/gen2/BugContest.lua` (815 lines; transcribed from `bug_contest/judging.asm`, `contest.asm`, `contest_2.asm`, `caught_mon.asm`, `bug_contest_mons.asm`) | implemented - `BugContest.score`, `rollContestant`, `judge`, `prizeFor`, `pickContestants`, `dropOffMons`, `returnMons`, `start/stop/tickTimer`, `chooseWild` |
| Contest comparison / debug UI | `src/ui/gen2/ContestMenu.lua` | implemented (a comparison screen, not the cart's HUD) |
| Contest super-tall-grass doubled encounter rate | `src/world/gen2/Permissions.lua:85` `SUPER_TALL_GRASS`, `BugContest.encounterRate` | implemented |
| Squirtbottle field check | `src/script/gen2/CallAsm.lua:411` `H.CheckCanUseSquirtbottle` (registered as `"14:4786"`), tested in `tests/gen2_callasm_test.lua:224-244` | implemented |
| **Using the SQUIRTBOTTLE from the PACK** | `src/world/gen2/World.lua:3294` `World:useFieldItem` | **missing** - the dispatch has arms only for `ITEMFINDER`, `BICYCLE`, `SACRED_ASH`, repels, trophy boxes and rods. There is no `SQUIRTBOTTLE` arm, so `_Squirtbottle` is unreachable from the PACK. The talk-to-the-tree path (`SudowoodoScript`'s `checkitem`) still works, which is the route the walkthrough takes |
| **Item ball pickup** (TM04 on Route 35, TM28 DIG and PARLYZ HEAL in National Park) | extractor reads them (`src/import/RomExtractorGen2.lua:2969` `obj.itemball = readItemBall(...)`) but `src/world/gen2/World.lua:5257` `World:interact` only dispatches on `npc.def.trainer`, strength boulders, `npc.def.scriptKey`, bg events and hidden items | **missing** - `OBJECTTYPE_ITEMBALL` objects have no `scriptKey` by design, and nothing consumes `obj.itemball`. A bot cannot pick up any of this section's three item balls |
| Hidden item (National Park FULL HEAL, Route 37 ETHER) | `src/world/gen2/HiddenItems.lua`, wired into `World:interact` | implemented |
| Fruit trees (MYSTERYBERRY, ICE BERRY, the Route 37 apricorns) | `src/core/gen2/Apricorns.lua` + the VM's `fruittree` branch | implemented |
| Overworld trainers, sight ranges, `loadtrainer` / `startbattle` | `src/world/gen2/Trainers.lua`, `src/battle/gen2/Battle.lua` | implemented |
| Phone numbers and rematch tiers (Irwin, Arnie, Jack, Beverly, Alan) | `src/core/gen2/Phone.lua` (Jack, Beverly, Irwin, Arnie, Alan all have callee/caller script keys and `..._READY_FOR_REMATCH` event ids) | implemented |
| Kenya the SPEAROW + FLOWER MAIL | `src/core/gen2/Mail.lua` + `Vm.lua:439` `givepoke` / `Vm.lua:462` `givepokemail` | implemented (extractor resolves `cmd.mail`) |
| CUT field move + `ENGINE_HIVEBADGE` gate + the Route 35 tree block | `src/world/gen2/FieldMoves.lua:104` (`CUT = "HIVE"`), `FieldMoves.somethingToCut`, `World:tryCutOW` | implemented |
| Sudowoodo wild battle + DRAW-flee branch | `src/script/gen2/Vm.lua:44` (DRAW), `Vm.lua:836` `loadwildmon`, `World.lua:5067` (`variablesprite` with a raw sprite id) | implemented |
| Driver / regression coverage for this specific stretch | `tests/drivers/gold_*.lua` | **missing** - there is no driver that walks Route 35 -> National Park -> Route 36, runs a contest, or fights Sudowoodo. `tests/gen2_contest_test.lua` covers the contest rules headlessly; `tests/gen2_callasm_test.lua` covers only the Squirtbottle facing check |
---
## 6. Unresolved / verify by hand
1. **"Talk to Floria... while she goes away to get the Squirtbottle."** No such script
exists in pokegold. `maps/GoldenrodFlowerShop.asm` has a `GOLDENRODFLOWERSHOP_FLORIA`
object at (5, 6) whose `FlowerShopFloriaScript` only prints text, and the girl on
Route 36 at (51, 8) is an anonymous `ROUTE36_LASS1` running `Route36LassScript`, which
also only prints text. The SQUIRTBOTTLE comes from `FlowerShopTeacherScript` gated on
`ENGINE_PLAINBADGE` alone, with no Route 36 precondition. The described sequence looks
like Crystal behaviour that leaked into a Gold/Silver walkthrough.
2. **Contest Pokemon list.** The walkthrough lists "Caterpie/Weedle, Nincada, Scyther,
Pinsir, Volbeat, Wurmple" at "Levels 28-31". `data/wild/bug_contest_mons.asm` has
CATERPIE, WEEDLE, METAPOD, KAKUNA, BUTTERFREE, BEEDRILL, VENONAT, PARAS, SCYTHER,
PINSIR at levels 7-18 (plus VENOMOTH 30-40 on the `-1` terminator row, which is never
selected). NINCADA, VOLBEAT and WURMPLE do not exist in Gen 2 at all. Treat the
walkthrough's list and levels as wrong for this game.
3. **"20 Sport Balls."** The item is `PARK_BALL` (`constants/item_constants.asm:185`),
given by `special GiveParkBalls`, count `BUG_CONTEST_BALLS = 20`. "Sport Ball" is the
Gen 3+ name.
4. **"If you win the contest, you can win a Shiny Stone!"** First place gives `SUN_STONE`
(`BugContestResults_FirstPlace`, `engine/events/std_scripts.asm:346`). The
walkthrough's own item list ("Sun Stone (1st Prize)") agrees; the prose line does not.
There is no Shiny Stone in Gen 2.
5. **"If you catch a Scyther at full HP, it may be worth around 342 points."** Not
verifiable from the asm without a concrete mon: `ContestScore` (`04:7cbc`) is
`MaxHP*4 + Atk + Def + Spe + SpA + SpD + DVbonus + HP/8 + heldItem`, all taken from the
high byte of each stat word. The walkthrough's qualitative claim ("score takes HP into
consideration") is confirmed; the specific number is not checked here.
6. **National Park species list.** The walkthrough lists Butterfree, Weedle, Kakuna,
Beedrill, Paras, Venonat, Scyther and Pinsir as "found in National Park". None of them
appear in `def_grass_wildmons NATIONAL_PARK`; they are Contest-only
(`data/wild/bug_contest_mons.asm`). Sunkern, Caterpie, Metapod, Pidgey and Hoothoot are
the only real National Park grass encounters in Gold.
7. **"Routes 36 & 37" item and species lists are merged.** Everything the walkthrough
attributes to "Routes 36 & 37" except the ICE BERRY, HARD STONE and TM08 actually lives
on Route 37 (`RED_APRICORN`, `BLU_APRICORN`, `BLK_APRICORN`; Ledyba/Spinarak/Pidgeotto),
which this section never enters. Vulpix/Growlithe and Stantler appear on both routes.
8. **"Route 35 & National Park" item list omits the hidden FULL HEAL** at National Park
bg (6, 47) and lists no hidden items at all. Not a contradiction, just incomplete.
9. **"Head back to Arnie and talk to *her*."** `BUG_CATCHER, ARNIE1` uses the male phone
std scripts (`AskNumber1MScript`, `RegisteredNumberMScript`). Cosmetic only.
10. **"Then, we're ready to head into Route 35 after Liz's offer for a rematch on Route
32."** Liz's rematch is a phone event outside this section's maps; no code on any map
in this section references it, so it was not resolved here.
11. **`EVENT_FOUGHT_SUDOWOODO` is set before the DRAW check** in
`WateredWeirdTreeScript`, and both the win branch and `DidntCatchSudowoodo` run
`disappear ROUTE36_WEIRD_TREE`. So the walkthrough's "catch it or else" is a
preference, not a gate - fainting or fleeing still opens the road and still unlocks
TM08. Worth confirming in-game that a *black-out* mid-battle does not leave a
half-applied state, which the asm alone cannot answer.
12. **`MAP_NATIONAL_PARK_BUG_CONTEST` warps 2 and 4 point at destination warp 1**, not 2,
in `maps/NationalParkBugContest.asm:228,230`. Transcribed verbatim; a bot pathing off
those rows should expect the asymmetry rather than assume a typo.
