After sneaking into his best friend Jimmy Neutron's laboratory and finding Jimmy's secret rocketship, Sheen Estevez accidentally blasts himself into outer space. Four million and one lightyears away, Sheen crashes on Zeenu—an odd planet inhabited by aliens called Zeenunians. Soon after the crash, Sheen wants to go home, but his rocketship was smashed when he flew into a house belonging to a Zeenunian named Dorkus, whose name Sheen ridicules for its similarity to the word "dork." Dorkus (who is one of the chief advisors 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 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 acquaintances, some of which include Doppy (a green, slug-like creature who resembles Sheen's friend on Earth, Carl Wheezer), Emperor (the grand head ruler of Zeenu, who firmly believes Sheen is a supernatural creature that will bring joy to Zeenu), Nesmith (an intelligent chimpanzee from Earth who excels in subjects such as math and engineering), and a Zeenunian girl named Aseefa who becomes Sheen's crush. Aseefa has a pet Choctow (the most feared and dangerous creature on Zeenu) named Chock Chock. With the help of his new Zeenunian friends, Sheen must fix his rocket, work for the Emperor, and annoy Dorkus as much as he can so he can get back home to Earth. It is currently unknown whether Jimmy or other characters from the previous series will appear; so far Carl has appeared in the show but only in a flashback, not in a physical appearance.
