Nickelodeon had 3 shows (Note: SHOWS, not movies) that they completely removed from their archives. The first was Happy Appy. The second was Fright House Screamers, a group of 4 teenagers who would spend the night at haunted places. Sort of like Ghost Adventures, but with teens. Only 3 episodes were made before one of the teenagers was found dead, with maggots crawling in him. Only a few pieces of information were leaked about the third one. It was a animated series about a kid who could use his superpowers to make fictional things. There were 1 and a half seasons released before the voice actor and 3 of the animators were killed in a bezerk fire. The reason why they removed the show from their archives is unknown so far.
