How does Uncle Bob do it? Owen couldn't figure it out. Buffalo Bob's Rootin' Tootin' Animal Circus is famous for its jump-roping giraffe, tangoing lion, and knife-throwing elephant. But they have to be fakes, right? Owen is determined to get to the bottom of this mystery. When he visits the circus he discovers that his uncle and, coincidentally, all of the animals, are missing. It can only be the work of Buffalo Bob's sideshow rival: Contorto. Owen stumbles upon the one thing that can save the day: Buffalo Bob's box of animal crackers. But these aren't any ordinary cookies: one bite and you're transformed into a circus animal! The audience is wowed by Owen's animal antics, but it will take more than a few carnival tricks to defeat Contorto and his pack of goons.
