12 oz. Mouse is an American surreal humour animated television series created by Matt Maiellaro for Adult Swim. The series revolves around Mouse Fitzgerald, nicknamed "Fitz" (voiced by Maiellaro), an alcoholic mouse who performs odd jobs so he can buy more beer. Together with his chinchilla companion Skillet, Fitz begins to recover suppressed memories that he once had a wife and a child who have now vanished. This leads him to seek answers about his past and the shadowy forces that seem to be manipulating his world.
In producing the series, Maiellaro crudely designed the characters as a cost-cutting measure; the series is animated by Radical Axis. He intended for the series to lack continuity starting from the pilot, but established a serial format after starting the second episode. He had constructed an ending for the series as well as a detailed map of characters; however, the series finale concluded differently from planned. Maiellaro cast people around his office for the characters, starring himself as the protagonist and Nine Pound Hammer vocalist Scott Luallen as the voice of Roostre; the band also performs the opening theme.
The pilot episode for 12 oz. Mouse, "Hired", premiered on June 19, 2005. The series became a regular staple of Adult Swim's lineup on October 23, 2005 and ended on December 17, 2006.
While this show does have somewhat of a cult following, Strider personally dislikes this show for its crudely animated designs and thinks Adult Swim put absolutely zero effort into its animation.
