Thwomp

Thwomps, also known as Thwomp Traps, are giant stone faces found mostly in the Mushroom Kingdom. They are normally depicted as spike-encrusted living stones that are usually rectangular in shape and made their first appearance in the game Super Mario Bros. 3. They typically attempt to fall on and flatten whoever passes below them, although some move horizontally or diagonally as well. They can be destroyed by Hammer Mario's hammers, Statue Mario, Gold Mario's fireballs, getting tapped while the player is under the influence of a Boost Star, a shell dash, by being touched when Mario is giant or invincible, or by a hammer swing from Builder Mario. Thwomps are sometimes described as "ghosts, '' and it is suggested in Mario & Luigi: Partners in Time that they may be born from volcanic activity.
