Muppet High was a planned television series that was never produced. The series was mentioned as having been in the works at The Jim Henson Company in 1990, in the months before Jim Henson's death. Muppet High was to depict the Muppets as 1950s high school students. A toy company, Presents, produced a line of merchandise in 1990 and 1991 showcasing the Muppets in their 1950s costumes -- a set of PVC figures, two Muppet High plush, and a set of Muppet High mugs.
