Tips
- Use the Itemfinder to find hidden Pearls (two), a Big Pearl, Stardust (two), a Star Piece and Ultra Balls (two); the gems and Star Piece are good to sell.
- Tangela is the main catch here, and it is just as common as Spearow in the grass.
- Version difference is Psyduck in FireRed and Slowpoke in LeafGreen, and when fishing FireRed has Horsea and Seadra while LeafGreen has Krabby and Kingler.
- Swimmer Amara uses Seel and Dewgong at level 36, so electric and grass moves work well.
