Despite direct instructions to stay out of trouble, the two young fish venture out from under their mother’s authority and into the deep blue sea, seeking what their hearts desire. Upon reaching the shipwreck, things immediately begin to get out of hand as they stumble on treasure, barracudas, and tourist advertising. In the end, only their father is able to rescue them from becoming a certain meal. Through these trials, Theodore and Fink learn a much-needed lesson on honoring their parents and authorities.
