Tips
- Caterpie and Weedle are the common wild Pokémon, and Metapod and Kakuna are less common; the less common of the two flips between versions.
- Pikachu has a small chance of appearing in both versions, making this the earliest place to catch one.
- Bring Antidotes or Potions since Weedle's Poison Sting can poison you, though you can also find several on the ground.
- The five Bug Catchers are easy opponents but worth fighting for experience before Pewter Gym.
- Pick up the Poké Ball, Antidote and two Potions, and check for hidden Potion and Antidote.
