Fatso had orange hair and wore a blue/white suit. He is morbidly obese from his hands to face. He was seen giving a Valentine's Day card to a woman when Klowns including Shorty, Rudy, Bibbo and Chubby were killing people door to door. The woman who got the card was so happy that she turned around not noticing that Fatso was about to kill her with his cotton candy gun. Fatso is actually the only Klown who had a very clear facial expression change, from smiling to frowning before he killed the woman with his cotton candy gun. He was also seen when he, Spikey and the other klowns chase after Mike and the others all through the entire space ship until Dave shot him in the nose, causing him to blow up to smitherreen off-screen.
