Hamburger Monster

The Hamburger Monster is in the episode Dad's Dungeon, along with the Hot Dog Monster in the first trial. It is possible that the hot dog and hamburger monsters could have had other appearances, as Finn notes Jake said he wanted hamburgers and Finn himself said he wanted hot dogs earlier in the same day. Jake kicks both of his heads off the monster, but like the hot dog monster it lives despite significant bodily harm. As they leave Jake tries to eat a lifeless looking burger arm that got caught in the rubble as the door caved in, but Finn slaps him.
