Curious George (2006)

S2E1 Up, Up and Away

George visits the Renkins' farm, excited to sample their delicious blueberries, but discovers Mrs. Renkins preparing a hot air balloon instead. She invites George and the Man for a short ride. As luck would have it, Bill arrives just in time, and in a moment of chaos, he and George inadvertently release the balloon from its moorings. Suddenly, the two find themselves floating high above the countryside, with no idea how to bring the balloon back down safely.
