The Muppets find themselves embroiled in a jewel heist in their second foray onto the big screen. Kermit, Fozzie and Gonzo attempt to restore their sullied journalistic reputations by identifying the thief who has been stealing gems from fashion designer Lady Holliday. “The Muppet Movie” involves even more spectacular scenes for this film, including a group bicycle ride in a London park, an aqua ballet “Miss Piggy style,” and a tux-and-tails dance sequence.
