Late for school, JoJo and Goliath bump straight into the Octopus Mailman, who has a very special letter for JoJo's class. JoJo gets to deliver the letter, which announces Terrific the Tiger Tamer's first annual dog-and-cat show. Skeebo and Trina decide to teach their respective dog and cat tricks and get some help from JoJo. Goliath is disappointed that he can't enter, but is cheered up by the idea of the upcoming lion show. Then, the time comes for the big show, with Harpo and Katrina each ready with a great trick.
