In Link's Awakening, Spiked Thwomps appear in side-scrolling areas of dungeons. They quickly drop down from a great height to crush any intruders below. This can be predicted when the Thwomp glares down below it, just before falling. After slamming down, they slowly rise up back into the air before falling again. Link can safely by-pass them by teasing the Spiked Thwomp by inching forward to initiate it to drop, then stepping back and walk by as it is slowly rises into the air. Alternately, it can also be quickly evaded by equipping and using the Pegasus Boots to run past. Unlike the normal Thwomps, only its bottom side is covered in spikes, and its top surface is flat. Link can jump on top of one as it lands by using the Roc's Feather. This becomes necessary to reach higher ledges in certain areas. Even when Link is standing on top of one, it will continue to slam down and rise, thus requiring Link to time his jumps to reach higher ledges. The enemies are completely invincible to all attacks and cannot be destroyed or stunned. They appear in Angler's Tunnel and Catfish's Maw.
