Diamond Island (WarioWare: D.I.Y. Showcase)

Diamond Island is the main location of WarioWare: D.I.Y. Showcase. On the main island are the Wario-Man Super Store and the Distribution Center while the Survey Box is on its own smaller island nearby. There are also some nondescript gray buildings, a pond, and roads on the main island. In 18-Volt's stage, he flies over the island which shows that parts of the island resemble the right-hand side of a Nintendo GameCube controller and a Family Computer controller.
