He is a giant monster with many green spikes sticking out of its back. His body is very long and serpentine, and has tentacles sticking out of its body that seem to end with green spikes, though some don't. He has long, skinny arms. His left wrist has the key to unlock the Demon Sword chained around it and one of the fingers has a spike on it. His teeth are similar to those of a Lub Glub. He has one eye that looks like a crystal with a pentagon inside. The eye glows very brightly when Finn stabs it.
- By the fact of its hands and eye being the only thing clearly shown and it being the last monster of the dungeon, it has many similarities with the monster Bongo Bongo from The Legend of Zelda.
- He also shares a slight resemblance to the Dark Fawful Bug, also known as the Dark Star Core, from Mario and Luigi: Bowser's Inside Story.
