Moldorm (The Legend of Zelda)

Moldorms are segmented enemies that first appear in The Legend of Zelda.

The Legend of Zelda
They are worms with many identical segments. They come out of the center of sandy rooms and start winding around. To defeat them, Link must hit the last segment, causing them to shrink one segment at a time.

The Legend of Zelda: A Link to the Past
Called Swamolas in the Player's Guide, they are green and leap out of the water of the Swamp of Evil in the dark world, acting similar to the Lanmola boss in the Desert Palace. However, they are much shorter.

The Legend of Zelda: A Link Between Worlds
Based off their A Link to the Past design and behavior, Moldorms appear in Misery Mire, itself essentially a renamed Swamp of Evil. Fiery versions called Flamolas appear in Turtle Rock.
