Thwomps are enemies in Super Mario Maker. It cannot be eliminated by any means other than falling out of the level or touching it with the Super Star or the Big Mushroom. A Super Mushroom can be applied to make it into a larger Thwomp. With Wings, the Thwomp will move around horizontally. Shaking a thwomp turns it into a Skewer
Trampolines, P-Switches or POW Blocks can be kicked up into the Thwomp to halt its fall. If it falls onto an enemy, the enemy is eliminated and the Thwomp keeps falling, and if it falls onto a Brick Block, the fall is slowed and the Brick is destroyed. If it falls onto a Note Block, it continues to bounce until something that halts the fall gets in the way. It will also bounce off a Buzzy Beetle Helmet. If a Thwomp is big, it will smash through layers of bricks and be able to smash Hard Blocks, Question Blocks, and Empty Blocks, but those will halt the fall.
