Serena is ready to compete in the Dendemille Town Pokémon Showcase—and so is her rival Miette, who once challenged her to a Poké Puff baking contest! As it turns out, the Theme Performance is all about Poké Puffs, and Serena, Miette, and Jessilia (Team Rocket’s Jessie in disguise) all advance to the Freestyle Performance.

After a run-in with Jessie that leaves a noticeable tear in Serena’s costume, she’s worried that this Showcase will end like her last one. But traveling with Ash has taught Serena never to give up, so she grabs her sewing kit to make a few last-second adjustments...and ends up winning the Freestyle Performance and her first Princess Key!
