Professor Elm caught Corsola around the Whirl Islands, where he was doing important research. He had Corsola accompany the heroes to save them from the whirlpools. After doing so, Corsola jumped into Elm's hands. After arriving on an island, Elm had Corsola join its friends at the pool. Just as Team Rocket captured Pikachu, Corsola went after them and tackled Arbok away. Using Spike Cannon, Corsola blasted Team Rocket away. Elm also joked that he should stay on Corsola's good side, seeing how powerful it was.
