assume she lives at a "highbrow" address. She sneaks into a townhouse at 17 Highbrow Street to wait for him (much to the surprise of the actual upper-class British residents), and they go out to the Dubonnet Club for dinner. At the nightclub, the real Lady Holiday's necklace is stolen by her jealous brother Nicky and his accomplices Carla, Marla, and Darla, three of her exploited fashion models (the very same thieves who robbed her before). After the robbery, Miss Piggy's charade is revealed and she flees, leaving Kermit behind. The next day; in a London park, they reconcile after having a brief argument. Despite Nicky's instant attraction to Miss Piggy, he and his accomplices frame her for the necklace theft during Lady Holiday's fashion show. They plan to steal an even more valuable prize: Lady Holiday's largest and most valuable jewel, the Fabulous Baseball Diamond, now on display at the Mallory Gallery. Unbeknownst to them, Gonzo overhears their plot. He, Kermit, Fozzie, and the other residents of the Happiness Hotel decide to intercept the thieves and catch them red-handed to exonerate Miss Piggy. Kermit arrives at the prison to explain the plan to Piggy, while being disguised as her "lawyer". The Muppets sneak into the Mallory Gallery and get to the Baseball Diamond at the same time as the thieves. They try to keep the diamond out of the thieves' hands via a game of keep away, but Nicky eventually catches the diamond and takes Kermit hostage at gunpoint. In the meantime, Piggy escapes from prison, and she races to the gallery, thus crashing through the window on a motorcycle that serendipitously fell off a truck in front of her. She knocks Nicky out and dispatches Carla, Marla and Darla with a flurry of furious karate chops. As the police arrive, all charges against Piggy are dropped, Nicky and his accomplices are arrested, and the Muppets get their deserved credit for foiling the heist. The Muppets then return to the United States the same way they departed, thus being thrown out of the cargo hold and parachuting back.
