Bill and Lt. Surge are searching for the Elite Four in the CeriseCave when they find a giant stone bridge with a giant "pond" under it. They decide to cross using the stone bridge. Bill then slips and falls into the "pond", but Bill's Magikarp uses Splash, putting Bill and Magikarp safely on the stone bridge. When Bill looks at his shoes, he sees that they have melted. Bruno appears and tells them that the stone bridge is a wildOnix, and that if they cross the bridge, victory is theirs. Lt. Surge accepts the challenge.
Meanwhile, in another part of the Cerise Cave, Blaine and Yellow are searching for the Elite Four, but haven't found a trace of them. Blaine borrows Yellow's Pokédex and checks the "Pikachu Emotion Mode" for Pika, and says that the levels are off the charts. Yellow tells him that he senses Pika will soon remember something important. Blaine suggests that after Red's battle with the Elite Four, Pika lost the memory of the battle. But there is no time to think about that, because they've just sighted Bill and Lt. Surge.
