Shark's Gun is a large military weapon that only ever appears in the episode "Meaty Dreamy", which was originally a weapon of Shark's grandfather but he gave the large weapon to him after the "meat wars" happened. Shark calls it a "one-gauge", which would "blow your head into vapor", "while it de-moleculizes your bones", as the Rectangular Businessman calls it a fake.
Later on, Shark and the businessman drive to a flaming Gas Station, having the large weapon in their car, as Shark claims "I'm to blow them away, all the away," and the businessman then claims "barely find your ass to clean it". The weapon them cocks at the businessman who knows Shark is going to blast off the weapon at somebody, soon a strange-acting man walks up to the window of their car, Shark fires the strange man with the weapon by his window, which blows him away, and his head falls off. The large weapon is never seen again after this.
