Thatkidsam.muffin/Mushroom Monster

Mushroom Monster is the Marshie-like mascot for Gruffy Guff Mushrooms, which Thatkidsam and Icreature seem to like. He takes the violent approach to his advertising, with a robot fight at the beginning of each commercial and the famous tagline, "BUY IT OR I'LL KILL YA!". His company uses slaves to pick the mushrooms, probably from Prance or the USA.
