Pokémon Season 1 Episode 34

The Kangaskhan Kid

Ash and his friends arrive at the Safari Zone, unaware that the part they have entered is a protected preserve when an Officer Jenny disguised as Chansey nearly arrests them for poaching. They come across a wild boy named Tommy that leads a herd of Kangaskhan and eventually find Tommy's parents, who were searching for him since he was only three. Unfortunately, Tommy thinks that the Kangaskhan are his family. After battling Team Rocket, Tommy's parents also become part of the Kangaskhan family.
