Jack comes up with the perfect new act to try to increase attendance at the carnival. He's going to have Marvin jump off a high diving board into a tub of water! Unfortunately, not only is Marvin scared of heights, but he's terrified of water too! Not wanting to disappoint his boss, Marvin keeps his fears a secret. In the end, he lands Jack in "cold" water, but learns that telling your friends you're afraid, is nothing to be afraid of.
- Marvin's hit Singin' in the Reins is parodied to Singin' in the Rain.
- In one page of the carnival history book, there's a picture of one of the penguins from The Penguin's Five.
