Mega Thwomp

A Mega Thwomp is a rare variant of Thwomp that only appears in an underground side-scrolling passage of the Key Cavern from The Legend of Zelda: Link's Awakening and its reissues. Both its appearance and behavior are significantly different than in the Mario games, especially the Super Mario series. Mega Thwomp is shaped like a large square, and its face consists of two eyes and an angry expression. It is stuck between two thin platforms, and is hanging in midair above a pit of spikes. Mega Thwomp serves more as an obstacle than an enemy because it does not attempt to crush Link if he goes underneath it. To move the Mega Thwomp, Link has to charge into it using the Pegasus Boots. In doing so, the Mega Thwomp cracks slightly, receives a shocked expression, and falls on the spikes below. With the Roc's Feather, Link can jump on to the Mega Thwomp and use it as a platform to go across the spikes and continue onward.

In both The Legend of Zelda: Link's Awakening DX and the Nintendo Switch version, Mega Thwomp is colored red. In the former game, Mega Thwomp turns blue upon cracking slightly, but in the Nintendo Switch remake, it stays red.
