Teach a Pokémon Headbutt (TM02 from Ilex Forest) and use it on trees. Whether a tree is common, rare or empty depends on the tree and your Trainer ID.

Chances are the game’s encounter slots for each time of day: morning 4:00–9:59, day 10:00–17:59, night 18:00–3:59 (grass and caves 30/30/20/10/5/4/1, surfing 60/30/10, Old Rod 70/15/15, Good Rod 35/35/20/10, Super Rod 40/30/20/10). Where Gold and Silver differ, a cell shows both (G and S); a version tag means the Pokémon only appears in that version here. Version exclusives · Where to find every Pokémon.

Items

Hidden items can be found with the Itemfinder from Ecruteak City.

Tips

• Take the Spearow from the Route 35 Goldenrod gate to the man on Route 31 for TM50 Nightmare; the Spearow must still hold its Mail.
• Bellsprout appears at any time of day; catch one to trade for Kyle's Onix in Violet City.
• Gold has Spinarak at night, Silver has Ledyba in the morning, and Rattata and Hoothoot come out at night in both.
• Pick up the Antidote and Poké Ball item balls, and the Bitter Berry from the tree each day.
• Bug Catcher Wade offers his number for rematches.
