Rah, Rah, Ra!.Chumley returns to Duel Academy, along with his boss, Maximillion Pegasus. Pegasus' chief card designer had stolen the Winged Dragon of Ra card and was using it in the Gx tournament. Chumley gave Jaden a new card to help him duel and he challenged the designer, Frantz, to a duel. Frantz was doing this because he was sick of Chumley getting all the respect for his cards and controlled Ra using a magic card to bound the dragon in chains. Jaden defeated him using the field spell, Skysraper 2- Hero City and Pegasus agreed to bring Frantz back.
