Amazing Island (Gamecube)

The Black Evil has taken over Amazing Island and captured its natives, the Maboo tribe. Now it's up to you to defeat the Black Evil, take back the land, and return it to its rightful owners. To do so, you must use your imagination to create your own monster and enter it in a series of competitions involving timing, speed, and head-to-head battles. The victor receives magical orbs that hold the power of the island and the keys to returning peace and prosperity to Amazing Island.
