Thinking that they are on a deserted island the grown-ups try to find a way to survive. Meanwhile Tommy and the other babies run into the Thornberrys! Tommy is sure that his hero, Nigel Thornberry can help them get off the island. But when Nigel bumps his head and is knocked out, he wakes up speaking baby talk! To make matters worse, the babies get stuck underwater in the Thornberrys bathysphere. With air quickly running out, the babies and Nigel find themselves in a race against time. Will they be able to get out before it's too late?
