Ash and friends are lost in a forest when they are attacked by a Skarmory that kidnaps May. It drops May on the other side of a tall fence, and several hooded men prevent Ash, Brock, and Max from pursuing.
The Skarmory drops May on the ground, where she saves a Bulbasaur from falling off a cliff. A group of Grass-type Pokémon angrily attack May, but she drives them back with Torchic’s Ember attack.
The hooded men explain to the guys that the Grass-type Pokémon will attack any human that trespasses, because people damaged the forest trying to catch Grass-type Pokémon. The guys decide saving May is more important, and Ash manages to get over the fence.
A group of Grass-types corner May, and Ash swoops in and has Pikachu clear a path. The two kids run for it, but get cornered again. A Venusaur arrives and orders the other Pokémon to back off, accompanied by the Bulbasaur that May helped.
May begins to befriend the Bulbasaur, but Team Rocket arrives, trying to catch Grass-types with their robot. May gets caught inside the robot as well, and helps all the Pokémon break free. The Venusaur uses Solarbeam to blast the robot away.
Reunited in the end, the kids get ready to depart the forest, with one new addition—the Bulbasaur decides to join May on her journey.
