Serena shows off her baking skills with a batch of Poké Puffs, sweet treats made especially for Pokémon! After a Slurpuff swipes them, she quickly develops a rivalry with its Trainer, Miette, who thinks her Poké Puffs are superior...and who seems to have a little thing for Ash.

Serena and Miette enter a baking contest to settle the score, and they both make it into the final round. But when they go out in search of berries to use in their next batch, they find that the local shops and the surrounding forest have been picked clean! Our heroes quickly discover that Team Rocket is sabotaging the contest, and with the help of Miette, Slurpuff, and some wild Swirlix, they send the villains blasting off again.

Serena and Miette find the berries they need, and after someone else wins the contest, they part with a friendly handshake and a promise of better baking next time. But this promise comes with a threat from Miette to reveal her crush on Ash if Serena doesn’t speak up first!
