From Muppet Wiki

Kermit's Electronic StoryMaker is a video game/book set that was made for the Commodore 64 in 1984. In the game, the player puts together a story using the words in the book. The player's choices then come to life as an animated story. Simon & Schuster also published a companion game, The Great Gonzo in WordRider.

A New York Times article described the game: "The Muppets of the television show -- Kermit the Frog, Miss Piggy, Gonzo, the whole gang -- act out sentences that the child at the computer console constructs, using the program's vocabulary. No matter how ridiculous, if it's grammatically correct, they'll oblige." ^[1]
