After accidentally drinking a potion that turns three young brats into pond life, Rickman's bored pilot fish discovers not only an ability to speak with a knowing cynical drawl, but a Sheriff of Nottingham desire to rule the ocean. "From henceforth oral hygiene is no longer my province," he declares to his dim Great White Shark.

Can the three human fish find the antidote that will turn them back into children before Rickman's power-crazed tyrant turns them into sushi? Don't hold your breath.

What the cartoon graphics lack in computer-generated muscle, they more than make up for in retro wit. If only the music could have lived up to the Busby Berkeley routines, the nod to Fritz Lang's Metropolis, and the Beatles gag (not just the title) in the LSD features of Rickman's garish fish. Still, kids of four and 40 will love it.
