Each crystal represents a sport that corresponds to the color of the crystal. There are four of them in total. The Sport Crystal is also the power source of the Star Ship. In the beginning of the Story, the Toads discovered that these Sport Crystals will help Mario and his friends introduce these sports to the Mushroom Kingdom so, a tournament is held to see who is the best player of the Mushroom Kingdom to receive these crystals.
