May has arrived at Lake Valor to see her old friends and compete in the Wallace Cup. She's brought presents for everyone and a new Pokémon, Glaceon—it's the new Evolution of her trusty Eevee, which she evolved in Snowpoint City. Always one for a good meal, May has lunch reservations for everyone at the Seven Stars Restaurant, a popular eatery where diners have to defeat the owner and his fiancé, Charleton and Charlene, before they can sit down to their meal. Ash and Brock partner up for the first tag battle, and easily defeat Charleton's Snorlax and Charlene's Munchlax with Pikachu and Sudowoodo.
May and Dawn are up next, and they're determined not to let the boys outdo them. Dawn chooses Piplup and May chooses Blaziken, while Charleton picks Girafarig and Charlene sends out her Drifloon. Before their battle can get into gear, there's horrible news: someone has just stolen all the food from the restaurant! The thought of no food has May seeing red, and she promptly orders Munchlax to sniff out the offenders. Munchlax leads everyone straight to Team Rocket, who are indeed gulping down all the gourmet fare. May and Dawn decide they'll have their tag battle after all by beating Team Rocket; a combination of Glaceon and Buneary puts Team Rocket on ice, while also earning May and Dawn their lunch ticket.
Since it'll take time for lunch to be prepared, May and Dawn decide they'll still have a tag battle with Charleton and Charlene, just for fun. Girafarig and Drifloon are hardly pushovers, but they're no match for Piplup and Blaziken's fusion combination of fire and ice. With the battle over, it's finally time to eat. Then, May gets caught up on the latest news as she and her friends prepare for the Wallace Cup, which promises to be a big event for everyone!
