Ash and friends are traveling to the Eterna Gym. They get to the Eterna Forest, and see a woman trying to catch a Burmy. She is using a Chansey, who uses Attract. Burmy is Attracted, and she seems very happy. Ash and Dawn comment that you have to attack a Pokémon to make sure you catch it. The woman takes their advice and Chansey uses DoubleSlap. Burmy uses Protect, but Chansey uses Egg Bomb, and the woman throws her Poké Ball. She catches the Burmy. She thanks Ash and Dawn, and tells them that she has three Wormadam. She throws their Poké Balls, and they come out to confirm what she said. She says that all her Burmy were females. Ash inquires why she wanted a male. She tells them she wants the end result to be a Mothim. Ash asks why again. The woman tells them her name is Cheryl, and she is a treasure hunter. She says she wants to fill in the empty space in her grandfather's collection of treasures, and needs just a bit of the Enchanted Honey, which is sweeter than any other honey. They say that they'll help.
Cheryl takes out her Burmy and tells the Wormadam to cheer him on. Ash takes out his Turtwig and tells it to go easy on Burmy. Burmy starts out with a Tackle, but it bounces off Turtwig. Dawn and Brock comment to themselves that the Burmy must be very weak, since it is supposed to have an advantage against Template:Type2. Turtwig uses Tackle back, and Burmy is thrown back. All his leaves fall off, and two cover Turtwig's eyes. Turtwig panics, and it accidentally tackles Burmy, who loses. Dawn says that Turtwig is being a little rough, so Ash calls it back. He calls out Pikachu. Pikachu uses a small Thunderbolt, which Burmy takes weakly. Cheryl tells Burmy not to give up, and use Tackle. Pikachu doesn't Dodge it, and pretends to be damaged severely. Then Team Rocket comes. They fly off with Burmy, to try to get it to evolve. Ash calls out Staravia to search for Burmy. It circles around where Team Rocket and Burmy are.
Meanwhile, Team Rocket sends out Seviper and Carnivine. Burmy loses, and Jessie shakes Burmy hard. James tells her to stop scaring the poor Pokémon. Burmy says that he's too hungry to battle Meowth, who translates. Once he's fed, Meowth battles Burmy and wins. First, they're all happy they won for a change, and then get mad at Meowth for winning.
Then, Ash and co. arrive, and start battling Team Rocket. It's 4 or 5 on 5, when Burmy evolves into Mothim. Team Rocket try to take off with it, but Ash doesn't let them get away. They blast off. Then, all is well until Mothim picks up a scent. They all run after Mothim, and the episode ends.
