One of my many planned April Fools threads for this year was for an announcement of a video game called "Muppets in the Labyrinth", which would have had Kermit going into the labyrinth to save his friends (similar to Epic Mickey: Power of Illusion having Mickey saving various Disney characters in a fantasy world). I was going to say that Disney and Henson were working on the production, so it would have also featured characters from The Dark Crystal, Fraggle Rock, The StoryTeller, Farscape, and maybe also Dinosaurs and Bear in the Big Blue House, in addition to Labyrinth characters (it'd be cool to see the Fireys and the devils from The Solider and Death together).
Of course there probably could be a Muppet game with that title, as "Labyrinth" obviously isn't a copyrighted term (since then there's been Sonic Labyrinth, Pan's Labyrinth, and Disney is making a new most-likely-unrelated Labyrinth movie).
