Every day, the game picks one random Mirage Spot (Mirage Island, Mirage Forest, Mirage Cave, Mirage Mountain, or Crescent Isle) to be accessible. More can be made available on a given day by interacting with other players through StreetPass. There are eight of each of Mirage Island, Mirage Forest, Mirage Cave, and Mirage Mountain, located in different areas; despite having the same name, their Pokémon and items differ, meaning the player must visit all eight to get everything.
