Teenage boys Tom (voiced by Bobby Resnick) and Tub (voiced by Barry Balkin) are rescued by the great white whale Moby Dick (voiced by Don Messick) after a shipwreck. Together with their pet seal, Scooby (also voiced by Messick), they face the dangers of the undersea world.
Moby Dick is stronger and faster than an average whale, and he can stretch his body to any length he desires. Some episodes also depict him as being able to command other sea creatures.
