Bubbles is a tiny fish with a big problem: no matter how hard they try, they cannot swim like the others. While other fish zip and dart, Bubbles drifts near the coral, watching with wide, curious eyes. Though their fins flutter, Bubbles only bobs and rolls, feeling a little out of place.

One morning a gentle wave pushes Bubbles close to the reef edge. The world beyond looks bright and full of movement — but it also feels scary. Bubbles takes a deep breath (as deep as a little fish can) and decides to try something new.
