Mystery Meat (Ghoulash)

Mystery Meat is a large chunk of an unknown meat and a character who only appeared in the Shocktober 2016 episode, Ghoulash. He was the main protagonist of the episode, as he was the last survivor of the attack by the evil Ghoulash. While cornered inside a sink, he defeated the beast by flipping a switch that turned on the garbage disposal, sucking the Ghoulash inside. However, the Ghoulash reached and grabbed Mystery Meat, and dragged him down the sinkhole, where it presumably kills him.

Personality
He seems heroic, and also cares about his friends a lot, as shown how upset he was when his friends died, especially Milk Box. Even though he deeply cares about his friends, he seems to jokingly tease them a lot, like when he said Gelatin was made of cow hooves.
