The Drop Block (analogus to a Donut Lift) is a part usable in Brawl's Stage Builder, and are also found in later levels of the Subspace Emissary. They are brown blocks with dark brown upside-down triangles on the sides. When stepped on for long enough by characters or items, these blocks shake, then fall. They eventually reappear. They only drop when they are stood on, so it is possible to make one way passages by sealing a narrow entry with a Drop Block.
