Toad is gardening flowers, when all of a sudden, an object crashes behind Princess Peach's castle. Toad then runs to the object (along with a few other Toads), and finds a red crystal containing a basketball, a green crystal containing a volleyball, a yellow crystal containing a dodgeball, and a blue crystal containing a coin (which serves as a hockey puck). While observing the mysterious crystals, the Toads come up with an idea of introducing new sports—basketball, volleyball, dodgeball, and hockey—to the Mushroom Kingdom. Toad then organizes tournaments for the four sports.
