Bug-Catching Contest
National Park’s mid-Johto mini-game runs Tuesday, Thursday, and Saturday. Bring one healthy lead, take 20 Park Balls and a 20-minute clock, then submit your best Bug for scoring. Hunt Scyther and Pinsir (5% each), farm Sun Stones, and use the live score tool below—wired to the same tables as the Mechanics Lab.
Fast answer
Enter on Tue / Thu / Sat → catch high-stat Bugs → score ≥ 376 for a lock
Reach National Park after the Goldenrod / Sudowoodo stretch (see SquirtBottle path). On a contest day, talk to the gate attendant. Your literal first party slot must be conscious; the game does not search later slots for a healthy lead. Catch with Park Balls only, keep the Bug healthy, and talk to the attendant again before time runs out. A catch that was generated holding an item gets +1, but it stays outside the party until judging, so you cannot attach an item yourself. Prefer Scyther or Pinsir for first place; both sit at 5% in the contest pool.

How to reach the park
- From Goldenrod: Route 35 north (Cut helps clear full path options) into the park gate.
- From Route 36: clear Sudowoodo, then use the Route 36 National Park gate.
- Contest attendants sit at the gates, not deep in the trees.
How it works
Contest rules (original G/S)
Party rule
The Pokémon in party slot 1 must be conscious and is the one that enters. The game does not scan for the first healthy Pokémon in a later slot. The rest of the party is temporarily hidden until you leave.
Balls & timer
You receive 20 Park Balls. Ordinary Poké Balls cannot be used inside the contest field. The timer is 20 minutes; talk to the attendant to end early when you are happy with a catch.
Judging pool
Five of ten NPC contestants are randomly kept. Each kept NPC score gets a random +0 to +7. Beat every selected NPC and you take 1st place; score 376+ always does so.
What you keep
- The Bug you submit for judging is retained regardless of placement, provided the party or current Box has room.
- You do not keep every Park Ball catch—only the judged submission matters for prizes.
- Heal and deposit plans: open the Catch checklist after you exit.
Held item +1
- A held item that the wild Bug already generated with adds +1 to the contest score.
- The catch is stored outside the party until judging, so you cannot attach a Berry, Mail, or another item during the contest.
- Pair with high Max HP and current HP for larger gains (see score tool).
Contest-only pool
All 10 Bug encounters
These rates apply only during the contest on the special park map—not the normal National Park grass tables. Gold and Silver share the same contest pool.

Contest score calculator
Formula: 4 × Max HP + Atk + Def + Spe + SpA + SpD + DV bonus + floor(Current HP ÷ 8) + held-item (0 or 1). DV bonus uses bit 1 of each DV (max +29). Enter the Bug’s battle stats at the moment you submit.
Stat inputs
How to read the number
- ≥ 376 — guaranteed first place (above every NPC max + variance).
- 350–375 — first-place contender; Nick’s Pinsir tops out at 375.
- 300–349 — podium range on average fields.
- < 300 — often loses to mid NPCs; keep hunting.
Tip: Max HP is worth 4× each other stat. A healthier, bulkier Bug usually outscores a frail glass cannon of the same species. Current HP still matters via ÷8.
Best place
Sun Stone
Evolution stone for Gloom → Bellossom and Sunkern → Sunflora. Best repeatable reason to farm contests.
Runner-up
Everstone
Stops evolution while held—perfect for breeding or keeping mid-stage movepools. Also appears elsewhere, but contest is an easy spare.
Podium
Gold Berry
Heals a large chunk of HP in battle when held. Useful filler prize while you chase first.
Consolation
Berry
Standard Berry if you finish outside the top three. This prize cannot be attached to the next contest catch before judging.
Benchmarks
All 10 NPC contestants
Each contest randomly drops five NPCs, then adds +0–7 to each remaining base score. Highest threat: Nick’s Pinsir 368–375 and Barry’s Pinsir 366–373.
Playbook
How to win (and farm Sun Stones)
1. Target Scyther / Pinsir
Both are 5% at Lv.13–14 but carry the contest’s highest natural scores. Weak them carefully—fainting wastes the encounter. Park Balls only; status helps.
2. Protect Max HP
Score weights Max HP ×4. Prefer a full-HP submission over a “cooler” mon you nearly KO’d. Heal if you have moves/items available before talking to the judge.
3. Check the generated item
The +1 applies only if the wild Bug was generated holding an item. You cannot move the contest catch into the party or attach a Berry before judging.
4. Scyther → Scizor plan
Contest Scyther pairs with Metal Coat + trade for Scizor. Track the line on the Catch checklist and Trade Planner.
5. RTC farming loop
Use the week calendar to hit all three contest days. Emulator clocks and VC RTC both count—change days carefully if you soft-reset schedules.
6. Lead Pokémon choice
Bring a lead that can False Swipe / sleep without struggling against Bug/Poison and Bug/Flying. Check moves in the Moves archive and legality in the TM/HM tool.

FAQ
Common Bug Contest questions
What days is the Bug-Catching Contest?
Tuesday, Thursday, and Saturday only. Sunday, Monday, Wednesday, and Friday have no contest. Use the days calendar if your RTC is skewed.
Is this different in HeartGold / SoulSilver?
Yes. This page is for original Game Boy Color Gold & Silver only. Remakes change schedule details, prizes, and park layout—do not mix guides.
Can I catch Scyther outside the contest?
In Johto play, the contest is the classic early Scyther source. Check the Scyther Pokédex page and live map search for every wild row on your version.
Why did I lose with a “good” Bug?
Five strong NPCs may have stayed in the pool, and each can roll +0–7. Compare your score to the NPC table—Nick/Barry Pinsir rolls up to 375. Aim for 376+ when you want a lock.
Do Gold and Silver have different contest tables?
No. Contest days, Park Balls, encounter pool, prizes, and NPC score bases match across both versions.
Where do I spend Sun Stones?
Evolve Gloom into Bellossom or Sunkern into Sunflora. Item pin: Sun Stone. Team ideas live in the best team guide and Team Planner.
