Moldorm (boss)

Moldorms are large versions of Moldorms that debut in The Legend of Zelda: A Link to the Past. Like their smaller counterparts, they move around erratically. They generally try to push Link off platforms to lower floors, and have a weak spot on the end of the tail.

One appears as the boss of the Tower of Hera. Defeating it grants Link the Pendant of Wisdom. One later appears in Ganon's Tower.

The Legend of Zelda: Link's Awakening
One is the first boss, of Tail Cave. This Moldorm looks angrier and spikier than the one in Link to the Past. It guards the Full Moon Cello. Later, one of the Shadow Nightmares takes its form.

The Legend of Zelda: Four Swords Adventures
It appears and is called Big Moldorm. It is gray and its tail end changes color depending on which Link needs to hit it. Midway through the battle, it splits in two. Ordinary Moldorms resemble the boss's appearance from A Link to the Past.

The Legend of Zelda: A Link Between Worlds
It again is the boss of the Tower of Hera, where it is yellow with several lumps on its top and a green fuzz around the rim along its underside. It now has the Pendant of Power. It is later found in the Treacherous Tower, alongside a stronger purple one, itself also found in Lorule Castle.

The Legend of Zelda: Tri Force Heroes
It appears with a design uncharacteristically resembling a Trilobyte or a horseshoe crab. Its large eyes indicate which Link needs to attack it, depending on their color. It is found in the Fire Temple and uses the nearby lava to its advantage.
