Drop Block

Drop Blocks are a type of block Wario encounters during the events of Wario World. They are mostly found in the Wooden Trapdoor and Steel Trapdoor sublevels, always in mid-air, and resemble floating, green blocks. When Wario steps on one, the weight causes it to descend slightly, pause, and fall quickly. If Wario is on the Drop Block when it falls, he may be forced to start the level over, particularly if he is inside a Steel Trapdoor's sublevel, which has no ground. The Drop Block returns to its starting position if Wario steps off of it.
