Tips
- The braille on the sealed door at the Dotted Hole spells 'Cut', so face it and use Cut to open the way.
- Several boulders in the valley need Strength to move, and the item balls here are an HP Up, a Full Restore and a Sun Stone.
- Ruin Maniacs, a Hiker and a PokéManiac guard the valley with Rock, Ground and Fighting types, so Water and Grass moves help against many of them.
- Wooper and Marill are version differences: Wooper in FireRed and Marill in LeafGreen, both in the grass and on the water.
- Natu, Yanma and Wobbuffet are in both versions, and fishing gives Poliwag, Poliwhirl and Gyarados.
