During the earthshake, the Sharptooth becomes trapped in an underwater cavern. This temporarily removes the threat of the predator and gives the children the opportunity to begin their journey to return Mo to his home.

The Sharptooth stops because it senses the ocean in the distance. As a creature of the sea, it is naturally drawn back to the water rather than continuing to pursue prey on land. Mo explains that the Sharptooth smells the ocean and chooses to return to its natural habitat.

Foreshadowing: Earlier scenes establish that Mo is from the Big Water, hinting at the ocean's significance to aquatic creatures.
