Shaggy and Scooby are tasked with eating all of that food before the demon can get to it to lure it out. The two are genuinely ecstatic to do so, binge for hours, and end up becoming not just incredibly round and fat, but roughly eight feet tall each and immensely strong. They then take on the Gluten Demon in a sumo wrestling match, as they're now "too full to be scared"; during the battle, both Shaggy and Scooby shrug off the damage of being thrown into several cars, while the cars themselves are totally destroyed.
