Jojo, a little blue fish, who is held up to his brothers' ridicule every day, is unexpectedly given the chance to assert himself, when he helps Flipper and Lopaka to save Dexter, who is buried alive in a submarine cave. So Jojo finally has confidence in himself, and a new-found respect from his brothers.

Lopaka and his friends put on a circus for the village. Dexter, who is watching off-shore, decides to put on a similar show underwater, as a money-making scheme. After the show, Dexter steals the circus equipment and takes it to Quetzo. Bolo accuses Lopaka of dumping the equipment, prompting Lopaka and Flipper to search for it.
