12 oz. Mouse is an American surreal humour and psychological thriller animated television series created by Matt Maiellaro for Cartoon Network's late-night programming block, Adult Swim.[1] 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.
The pilot first aired as a special presentation on June 19, 2005, and the series later started officially airing from October 23, 2005, until ending on December 17, 2006, with a total of 20 episodes over the course of 2 seasons. A special, entitled "Spider-Man Special", aired on November 6, 2005, and a stand-alone webisode, entitled "Enter the Sandmouse", was later released online on May 16, 2007.
In 2018, a double-length special, entitled "Invictus", aired on October 14 and it was announced that 12 oz. Mouse had also been revived as a series.[2] The final episode of the third season originally aired unannounced on April 1, 2020, as part of Adult Swim's annual April Fools Day stunt. The first 10 episodes from the third season premiered nightly (except weekends) from July 20 to July 31, 2020.[3]
