However, he did not draw Skillet and Shark, because Shark's model was used in other adult swim shows such as Sealab 2021, Space Ghost Coast to Coast and Aqua Teen Hunger Force, and Skillet was a drawing in a old clip art book, which was revealed in a B&W Bumper on Adult swim when Maiellaro was asked by a viewer why Skillet was the best drawn character in the show.
