Pokémon Emerald Tips

Mirage Island
On really, really rare occasions, you may encounter Mirage Island in the middle of Route 130. Whoever encountered the island was really lucky, as this island is painstakingly rare to find.

To find out whether Mirage Island will appear, talk to the old man living in one of the houses in Pacifidlog Town. If he says "I can't see Mirage Island today", that means the island isn't there. However, if he actually does see it, surf to the middle of Route 130 to find Mirage Island.

Wynaut are the only Pokemon that can be found there. Not only that, there is also a lone Liechi berry. It is the only one in the game, so you MUST plant it if you want to get more of it.
