37화: 아시와 친구들은 듀플리카의 디도가 얼굴을 바꾸는 데 애먹는 저택을 방문하고, 로켓단원들은 이를 훔치려 꾀를 부린다.

37

During a storm, Ash and his friends arrive at a mysterious mansion. While there, Ash meets Duplica (イミテ, Imite), a girl who is an expert at impersonation, and she happens to own Ditto, a Pokémon that can transform into any Pokémon. However, Ditto cannot seem to figure out how to change its face, a fact that stopped Duplica's variety show. As they all try to help Ditto perfect its transformation, Team Rocket tries to steal the Ditto so it can transform into a Dratini which they can give to the boss. (Source: Wikipedia)
