Muppet Adventure: Chaos at the Carnival is a video game released for the Nintendo Entertainment System in 1990 by Hi-Tech Expressions . It is similar to but not a direct port of the game of the same name released for the DOS platform in 1989. The game features an obvious promotional tie in with but is only superficially related to the Muppets created by Jim Henson.

Game play

The game consists of five largely unrelated minigames. The main objective is to rescue Miss Piggy from the "Grumpasaurus", a being who has kidnapped her. In order to complete this objective, the player must assume the role of four different muppets (Kermit the Frog, Fozzie Bear, Gonzo and Animal), direct them in the collection four keys and subsequently confront the "Grumpasaurus".
