context: When Clifford, Emily Elizabeth, and their friends visit the fair, Clifford, Cleo, and T-Bone are amazed by a terrible animal act known as Larry's Amazing Animals, consisting of Shackleford the Ferret, Dorothy the Cow, Dirk the Dachshund, and Rodrigo the Chihuahua. After the show, Shackleford discovers that the only way for their performances to continue is to win a Tummy Yummies Animal Talent Contest, promising fame, fortune, and a lifetime supply of Tummy Yummies. Clifford and his friends come to collect their autographs, and Shackleford attempts to convince them to join, believing Clifford's appearance will help them improve, however, none of them agree because they would not want to leave their owners.
  The next day, Clifford overhears the Howard's conversation with their neighbor. He mistakenly believes he's a financial burden on the family and decides to join the Amazing Animals, with T-Bone and Cleo joining him. After escaping a town afraid of Clifford, the group finds Larry's animals. Since Larry cannot accept animals with owners, they dispose their tags, claiming they're to trick dogcatchers. Clifford helps the others improve their acts and immediately becomes the star of the show, much to Shackleford's annoyance. Meanwhile, Emily Elizabeth searches for Clifford and finds out he ran away.
  Larry's Amazing Animals finally receives entry for the Tummy Yummies contest, and Shackleford tells Clifford how much he despises him, causing him to get angry and leave, although Cleo and T-Bone convince him to return. Larry's Amazing Animals wins the contest, but the CEO of Tummy Yummies, George Wolfsbottom, steals Clifford for his spoiled daughter Madison.
  At a hotel, Shackleford tries to get everyone to realize Clifford just wanted the Tummy Yummies, prompting a furiously disgusted Cleo to expose his true intentions. Shackleford realizes he was wrong about him and show the tags to Larry, and he contacts Emily Elizabeth. The animals break Clifford out of his cage, but T-Bone accidentally sets off the alarm. The group narrowly escape, but Emily Elizabeth arrives on time to claim Clifford before Wolfsbottom could get him. Clifford reconciles with Shackleford, and he, his friends, and Emily Elizabeth return to Birdwell Island.
