an American CGI animated television series. It is the second spin-off of the 2001 film Jimmy Neutron: Boy Genius. The series was picked up for 26 episodes by Nickelodeon for its first, and only season. Jeffrey Garcia returned as the voice of Sheen, and Bob Joles and Rob Paulsen are the voices of Nesmith and Doppy. The series was originally produced by C.O.R.E. in Toronto, but 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) in the United States. The series aired its final episode on February 15, 2013.After sneaking into Jimmy's laboratory and finding Jimmy's new rocket ship, Sheen accidentally blasts himself into outer space when he disobeyed Jimmy's warning note ("Sheen, do not press this button") and pressed the button Jimmy mentioned in his note. Four million and one light years away, Sheen crashes on Zeenu—an odd planet inhabited by aliens called Zeenunians. Soon after the crash, Sheen wants to go home, but his rocket ship was smashed when he flew into a house belonging to a Zeenunian named Dorkus. Dorkus (who is one of the chief advisers to the Emperor) is furious that Sheen destroyed his home, and intends to destroy him. Unfortunately, the Emperor takes a liking to Sheen and thwarts his plans at every turn. Much of the show is centered around Sheen fixing his rocket, working for the Emperor and annoying Dorkus with his antics and wild destruction, and Dorkus trying (and failing) to get back at him for it. While on Zeenu, Sheen makes many new friends, some of which include Doppy Doppweiler (a green, slug-like creature who resembles Carl), the Emperor (the grand head ruler of Zeenu, who firmly believes Sheen is a supernatural creature that will bring joy to Zeenu), and Nesmith (an intelligent chimpanzee from Earth who excels in subjects such as math and engineering).
