In Ballooning, some inhabitants of Mammoth Island decide to explore the far side of a distant mountain ridge on a breezy spring day. Halfway up the steep mountain trail, their trusty mammoth becomes afraid and winds up trapped on the mountainside. In order to save their hairy friend, Olive and Troy enlist the aid of the inventor to build a hot air balloon. Their plan involves using the balloon to float back up the mountain, where they harness the mammoth and carry him safely back to the village.
