While Russell goes off to save Kevin, who is being held prisoner in Muntz's dirigible, Carl relaunches the house and goes after Russell. Russell has been captured, tied to a chair, and the chair situated at the top of an open runway. As Russell's chair slowly slides down the runway and is about to plummet to the ground, Carl steers the house close to the runway and saves Russell, pulling him back into the house. He tethers the house to the runway, and he and Dug enter the dirigible to save Kevin. Carl lures away Muntz's dogs by tossing them a ball from the end of his walking cane. He releases Kevin from his cage, but Muntz corners them in the room and goes after Carl with a sword. Just as Muntz is about to run his sword through Carl, Dug accidentally brushes against the dirigible's steering stick, causing the airship to tilt. Meanwhile, Russell has managed to steer the house close enough to the dirigible so that Kevin and Dug can come back into the house. Muntz follows and start shooting at them. Carl lures Kevin with a piece of chocolate, and Kevin flies out a window with both Russell and Dug hanging onto him. Muntz tries to follow, but get his foot entangled on the balloon strings and goes plummeting toward the ground. The house sails off on its own. Kevin stays behind on Paradise Falls to raise her chicks, and Carl, Russell, and Dug pilot the dirigible back home. When Russell's father doesn't show up at his Senior Explorer celebration, Carl steps in to receive Russell's honor. Carl bestows upon Russell his own badge...the Ellie grape soda badge, and then takes Russell out for an ice cream. Unbeknownst to Carl, his house has finally settled down next to Paradise Falls, just where Ellie wanted it.
