Mirage Island
Mirage Island is exactly what it sounds like: a mirage. Or is it? If the conditions are right, Mirage Island will appear in the middle of Route 130.
In order for it to appear, you need to have a "Mirage Island friendly" Pokémon. These are Pokémon generated by a certain numerical code by the game randomly. You can check and see if you have a Mirage Island friendly Pokémon with the old man in Pacifidlog Town. He'll normally say he can't see Mirage island today, but if you do have a Mirage island friendly Pokémon in your party, he'll be able to see it. Show him every Pokémon that you can to increase your chances of seeing it.
What's on Mirage Island?
Honestly, there isn't much here. You'll find high level Wynauts', and the very rare Liechi berry here. There's nothing else here otherwise. Kind of a disappointment considering how much effort it takes to get here.
