off to find her with the family cat Snowbell, convincing George to conduct a series of elaborate (and extremely unconvincing) lies to Eleanor in order to cover for him. Stuart and Snowbell seek out street-cat Monty, who tells them that Falcon lives at the top of the Pishkin Building, and warns that he is an extremely dangerous foe. Stuart uses a balloon to fly to the summit of the Pishkin Building, but is taken aback when Margalo reveals her alliance with Falcon. Falcon traps Margalo in a paint can, and attempts to kill Stuart by dropping him from the sky; Stuart instead lands in a garbage truck and is taken to a garbage barge out at sea. Initially devastated at the series of events, Stuart soon finds his silver lining by rediscovering and subsequently repairing George's broken toy plane, which he uses to fly back to land. Meanwhile, George, after being reprimanded by his parents for lying, confesses Stuart's whereabouts to them, prompting them to head out and look for him. In the meantime, Snowbell has also ventured up the Pishkin Building, and frees Margalo from the paint can, only to become trapped in it himself. Margalo breaks free from Falcon's control, and flies away with Eleanor's ring, prompting Falcon to give chase. Stuart arrives in his toy plane, and a furious chase occurs through New York, with the Littles following from behind. Stuart ultimately wins the battle by using the ring to blind Falcon's vision, before jumping from the plane and allowing it to crash into Falcon as he falls into a trash can and is possibly eaten by Monty. The day saved, Frederick and Eleanor forgive Stuart for running away and George for lying to them, and tell them they are extremely proud of them for their bravery. Later, Margalo fulfills her dream of flying south for the winter, planning on returning to the Little household in the spring. Martha stuns everyone by using her first words to say goodbye to Margalo. Cast Live-action cast Geena Davis as Mrs. Eleanor Little, the mother of the Little family and Frederick's wife.
