Real name Charlie, he lives in a cyst inside a cave in the overflesh. His full appearance is never revealed, with only his yellow glowing eyes being visible. It's most likely that he is a worm but that was never confirmed for sure. Unlike most worms (who are jerks), Charlie is helpful and offers a weapon to Fern to defend herself.
In Awful Hospital.
- His real name is revealed when the Chest Worm speaks to him.
- He is a reference to the "It's dangerous to go alone!" meme from the game The Legend of Zelda.
