The Tentacle Monster is a creature that first appeared in the episode “Mystery Dungeon” as one of the Dungeon's many obstacles. He was defeated by the Earl of Lemongrab after he squirted his “essential juices” into the monster’s eyes.


The monster is dark red with a dragon-like face. He has two giant legs with many tentacles instead of hands. He also has three eyes, and a huge set of teeth.
