Several other species were explored, including the Spooble, the morphing Phoob, and the Merdlidops. On one occasion, a group of Fazoobs auditioned for Kermit. In Muppets Tonight episode 101, Nigel tells the crew to run the tape of the Koozebanian dance number, which features members of the Extremes, suggesting that they may be from Koozebane. The planet would also be featured later on Muppet Babies, Little Muppet Monsters and City Kids.
