Planet Sheen is an American animated television series created by Keith Alcorn and Steve Oedekerk. It is a spin-off series of the Jimmy Neutron franchise, the second sequel television series of the film Jimmy Neutron: Boy Genius, and also a sequel to the television series The Adventures of Jimmy Neutron, Boy Genius. The series was picked up for 26 episodes by Nickelodeon for its only season. Jeffrey Garcia returns as the voice of Sheen, and Bob Joles and Rob Paulsen are the voices of Nesmith and Doppy. The series was originally animated by C.O.R.E. in Toronto, but animation production moved to Bardel Entertainment in Vancouver after C.O.R.E closed down. At that time, Chris Neuhahn took over as Supervising Producer. Planet Sheen premiered on Nickelodeon on October 2, 2010 (along with T.U.F.F. Puppy, which premiered a half hour later) in the United States, and then aired its final episode on February 15, 2013.
