The episode starts when Finn and Jake see Wizard Battle. When Ice King is caught cheating, Finn and Jake enter in the competition to stop Ice King. While in the competition, Finn and Jake (as Magic Fist ) meet Abracadaniel who claims that if he won, he would 'turn and push', meaning he would not want Princess Bubblegum's kiss.
At the end of the wizard battle it was only Ice King,Giant Fist and Abracadaniel left. Abracadaniel wins using his wizard powers and Giant Fist forfeits the battle, which is when the Grand Master Wizard turns Finn into a cat. When Abracadaniel says that he "deserves a kiss from a princess," Finn rips through the cat skin and KOs Abracadaniel using the most frowned upon magic of all, a "power screech," but since he was the last one in the battle, he was victorious.
When Peppermint Butler is singing and Giant Fist is walking up to kiss Princess Bubblegum, Rock Wizard trips Giant Fist, revealing that he is actually Finn and Jake. Princess Bubblegum kisses Finn for saving her from the Ice King, but slaps him right after for breaking Wizard Battle rules. While they are laying there, Finn puts his glasses on Jake and says he looks "so fly." Ice King then walks up to them, also wearing glasses asking them for their rating from 1-10 .
