Dudley Moore originally introduces M.A.M.M.A. to Kermit as his back-up to be used for "Mama Don't Allow" in place of the Electric Mayhem. The members of the band naturally protest this, and say that if they're going to be replaced for that number, then the machine might as well play music for the entire show. After their introduction, Kermit muses that M.A.M.M.A. looked like a "Reject from Star Wars." As a result, the robot appears in several sketches, and even provides a dramatic climax for a conversation between Kermit and Miss Piggy in her dressing room.
