Rover the Watchdog Fish is a multigenerational portal of family fidelity, individual fortitude, and courage. Dubbed the littlest goldfish in a pet shop, this heroic fish awaits adoption. Since birth, he has been told to "stay in his bowl and follow the ways of other fish," but he believes life has another path for him. Despite usual practices in a pet store, he wants to remain with his foster parents and friends, so he aspires to other goals. The intrusion of a burglar one inauspicious night gives this miniature hero an opportunity to demonstrate more and fulfill this dream. Rover learns even the smallest action can make a major difference.
