The Great Space Coaster Telethon

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 (host of The Gary Gnu Show). 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.
