There is a shop located on the map for purchasing power-ups, each worth a certain number of coins that the player earns from the minigames or Bowser Jr. In order for a Captain to use their special abilities, they must be purchased from the shop; these power-ups are permanent, and can be carried over into other Challenge Mode games by continuing from a previously cleared game. Other power-ups offer a temporary boost to a stat for all characters on their team, but they only last for one game, win or lose. A Toad runs the shop.
