The puppies board a double-decker bus, but Cruella and the Baddun brothers discover the escape and pursue them in their stolen truck, racing through the streets of London, and crashing through the filming of Lightning's new show. Cruella and the Baddun brothers finally corner the puppies in an alley. Patch tries to hold them off while the others escape, but they are undaunted. Luckily, Thunderbolt arrives, having been driven to the scene by Lars, and fakes a heart attack, distracting Cruella and causing her to knock out Jasper and Horace and incapacitate herself. Patch puts the bus into reverse, sending Cruella, the Baddun brothers, and Lightning scrambling into the River Thames, along with their stolen truck. Patch and Thunderbolt survey the scene, both letting out deep, heroic barks. The police arrest Lightning and Cruella who, now driven completely insane, is sent to a mental institution, while Jasper and Horace confessed their actions to the Radcliffe family that Cruella was the one behind the kidnappings, the charges were dropped, pardoned, reformed and started their own shop of sundresses. Pongo, Perdita, The Radcliffes, and Nanny arrive, and Patch's parents tell him they are proud of him. Thunderbolt dismisses himself as just an actor, but says that Patch is "a real, one of a kind wonder-dog".
