In this one-hour special, Kermit the Frog throws a glamorous party at the Cocoanut Grove nightclub to celebrate the premiere of the Muppets' first feature film, The Muppet Movie.

- Miss Piggy shows some footage from "The Muppet Movie" to Rita despite Kermit's objection.
- Kermit tells Dick van Dyke that he and the Muppets are staying at Bide-A-Wee Motor Court since it's the only area that gives the Muppets a good rate and they allow livestock. Kermit and Dick laugh at this until Miss Piggy karate chops both of them.
