Cloyster was used along with Cassidy's Tentacruel in their attempt of capturing and stealing Moltres. The two fired Water Gun at Moltres, who dodged the attack, but was caught in a net. To help Moltres, Silver sent Salamence to free Moltres, then attacked Team Rocket. The latter had their Pokémon repeat their attacks on Moltres, capturing it in a trap.[1]
