Sham and Carl had their Persian and Houndoom use Roar on Gold and Crystal, preventing them from moving. Thus, Gold's Aipom used its tail to send a Politoed, whose Hypnosis forced Houndoom and Persian to fall asleep. This stopped them from using Roar, allowing Crystal and Gold to continue their battle against Carl and Sham.
