With Dawn and her friends safely past the appeals round of the Wallace Cup, the girls enjoy an opportunity to sit back and chat while Ash, who can't sleep, decides to take a walk near Lake Valor. He gets the shock of his life whenhe sees a glowing entity above the lake, which just might be a Legendary Pokémon like the ones said to live in Lake Verity and Lake Acuity! But any further investigation will have to wait until the next morning, after the Wallace Cup resumes.
As the battles begin, size proves to be no obstacle for Dawn's Buneary as it uses acrobatic footwork to defeat its opponent Wailmer. This round is off to a great start for Dawn, but Jessie is depressed that she didn't even make it to this stage of the Contest. Fortunately, James and Meowth remind her that she can always pose as a Contest reporter to get back in the spotlight. Dawn clinches a place in the semifinals, and then it's time for Ash and Buizel to battle Kyle the Coordinator and his Lanturn.
Kyle has had plenty of time to study Buizel's moves, an edge which helps him knock Ash out of the competition. With Dawn through and Ash out, that leaves May and Zoey still to compete. They win their matches and advance to the semifinals, so Dawn will definitely have to face either May or Zoey if she wants to win the Aqua Ribbon! But to get to the final round, she'll have to defeat Kyle and his Crawdaunt—is her Piplup up to the task?
