Template:Incomplete synopsis
Crossing a hill on the way to Goldenrod City, Ash and his friends notice a building nearby. As Brock is about to say what he thinks the building is, a Wooper drops from a tree and lands on Brock's neck, causing him to fall down the slope.
On the lower level, Olesia is about to teach the class of Wooper when Brock hits the ground. Wooper then jumps off Brock and Olesia asks if he is alright. Brock quickly recovers and starts flirting with her. Misty pulls him away and then asks Olesia about the buildings. She tells them that it's a preschool only for Wooper. She then tells of how she loved to raise Wooper, and how that spot was a good place to teach. Ash then goes to his Pokédex and looks up Wooper. Ash reminds himself of his previous encounter with the Quagsire. Misty then asks Olesia if they could watch her teach and she agrees. She plays the tambourine and then the Wooper start to swim and dance. Ash and Misty then admire the Wooper while Brock admires Olesia.
In the woods, Jessie is looking around for food when she finds a mushroom. James and Meowth tell her that it is poisonous. She tosses it aside and all three start to complain of how they haven't had any food for weeks. Then James says that they could call the "the Boss" for money but then is told by Meowth that they spent all the money he gave them. They decide their only hope is to find a rare Pokémon. Wobbuffet joins the trio and they start looking around for either a rare Pokémon or a snack.
Ash and his friends are having their snack when Olesia gets a call from her mom. Olesia then says that her mom needs to see her. Brock then offers to take care of the Wooper while she is away. She accepts, gives Brock a book about raising Wooper, and drives off in her Motorcycle. They head inside the preschool.
Inside, they discover the Wooper aren't in the pond. Ash's then finds a trail of water leading deeper inside the house. They follow the trail and find the Wooper eating and all over the place. Brock then reads in the book that the best way to get Wooper to listen to you is to show affection and food. So Brock pulls out a piece of food and shows it to the Wooper. One Wooper walks up and licks him and then the rest proceed to do so too. He then reads that the second best way was to play the tambourine. Misty then remembers of how she used to play the tambourine when she was a little girl. She picks up the tambourine and begins to play it, but none of the Wooper seem to be entertained. She then puts it down and they begin to leave; she then realizes Togepi is gone. They hear a tambourine playing, and they see Togepi playing the tambourine and the Wooper following Togepi.
Misty is angry that they'd rather listen to Togepi's beat rather than her own. Brock says it's just because Pokémon know a Pokémon's beat.
