Trapdoor (Wario World)

Trapdoors are doors that lead to Bonus Areas, found in the game Wario World. There are two types of trapdoor: wooden and steel. Wooden Trapdoors had small obstacle courses, which were usually underground. He can enter them by Ground Pounding them. They rewarded him a Red Diamond, and possibly a Golden Statue Piece.

Unlike Wooden Trapdoors, which could be entered with a Ground Pound, Steel Trapdoors required a Piledriver to get through. Once inside, Wario would find himself in an expansive obstacle course in the sky, with no solid ground at all. Falling off the floating platforms would force him to start over. At the end of the obstacle course a Red Diamond would always be found. Sometimes, a Golden Statue Piece would be there as well.
