When Gator, Ribby and Newt go in search of food, they make a fishing rod from an old bicycle. The bicycle is so big that everyone has to work together to make it work. After fishing for a while and catching nothing, the crew gets bored. Out of nowhere something huge pulls the line! Gator and Newt start jumping on the pedals and pull back the line. Suddenly they are thrown into the air. From below the surface of the water appears a giant rainbow bubble fish, the fish has so many beautiful colors, but it looks very grumpy and sad. The giant rainbow bubble fish, Rainy, is even hungrier than the crew. Together, they come up with a plan to get apples from the tree. As Rainy devours the delicious fruit, something wonderful happens. With a musical melody, a colorful rainbow sprays from the Rainy blowhole!
