S07E34 Hokey Poké Balls!

Since May has Bulbasaur on her team, Ash decides to summon his own Bulbasaur for a reunion. Meanwhile, Team Rocket has tampered with their transport machine, enabling them to snatch the Poké Balls being sent over. During the ensuing skirmish, Team Rocket blasts off with the stolen Poké Balls. Luckily, Ash's Bulbasaur comes back just in time and joins forces with May's Bulbasaur to track down Team Rocket.
