The Great Space Coaster Sticker

The Great Space Coaster is about three young singers (Francine, Danny, and Roy) who are brought to a habitable asteroid in space called Coasterville by a clown named Baxter who pilots the "space coaster", a roller coaster-like spaceship. The asteroid is populated by strange-looking, wise-cracking puppet characters such as Goriddle Gorilla, Knock Knock the Woodpecker, Edison the Elephant, and Gary Gnu. Baxter is forever on the run from M.T. Promises, a nefarious ringmaster who plans to re-capture Baxter and return him to the circus he worked at before he escaped. Each episode ends with a different life lesson, and various celebrity guest stars (such as Mark Hamill of Star Wars fame and composer Marvin Hamlisch) occasionally dropped by.
