Danny Phantom was an American animated television show created by Butch Hartman for Nickelodeon, produced by Billionfold Inc. It is a sister show to The Fairly OddParents alongside T.U.F.F. Puppy. The show was about a teenage half-ghost boy, who frequently saves his town and the world from ghost attacks, while attempting to keep his ghost half a secret. It is distributed outside the United States by the Canadian animation company, Nelvana, the same as The Fairly OddParents. The show in certain ways is linked to FOP. For example, in Fly Boy, Dash Baxter makes a cameo appearance. The episode Poltergeeksis a parody of the show. In addition to this, there's a Crash Nebula video game shown in one of Danny Phantom's episodes. This would seem to suggest that The Fairly OddParents and Danny Phantom take place in the same universe.
