Tips
- Pidgey and Caterpie are the main catches; Caterpie evolves quickly into Butterfree and is a decent early pick.
- Three Potions, a Poké Ball and an Antidote are scattered around, and the Antidote and one Potion are hidden, so check the dead ends.
- Bug Catchers dominate the trainers here, so Fire and Flying attackers make short work of them.
- A rare Pidgeotto turns up in the grass if you are patient.
- Heal up before the exit gate, because Pewter City's Gym is next and Brock uses Rock-types.
