mirage island mirage island mirage island mirage island
you find mirage island outside pacifidlog town when you have a mirage sensitive pokemon. you have to talk to an old man in the southeast corner of town without a hat. if he says "i can see mirage island today!" then then you have a mirage sensitive pokemon and can visit mirage island on route 130 or 129
Mirage Island appears when you have got a Wanuat. Sometimes Mirage Island appears and sometimes it doesn't - the old man will normally say " I can't see Mirage Island today" but rarely he will say he can - and that's when it appears. DO NOT let your Wanuat evolve otherwise you will not find Mirage Island.
Check youtube ;-)
