The group ends up in the middle of a carnival. Ash and Brock decide to enjoy themselves by changing into funny costumes and they start dancing. Misty and Pikachu walk away from them, very embarrassed. While eating ice cream, Misty and Pikachu see a man who is getting yelled at by woman in a Vulpix girl costume because he couldn't pay her. The woman hits the man and walks away. The man sees Misty and asks her to be his assistant in his magic show since his old assistant just quit. He introduces himself and says his name is Melvin. Misty agrees to help him, but only once. Misty is forced to wear a Goldeen girl costume with fins. She was embarrassed but the crowd was small so she felt less embarrassed until Ash and Brock show up in time to see the magic show and laugh at Misty. He then tries to conjure some flames but all that came out was a puff of smoke. He tries it again but this time it worked. Unfortunately he gets a little carried away. Misty tells him to be careful, but he ignores her. The sprinklers go off and the magic show is ruined.
Melvin is fired as a result. Misty tries to comfort him but he wants to give up his career. Ash gives him some help by doing his own magic trick using a magic box that has water, fire, and vines in it. The box really has Squirtle, Charmander, and Bulbasaur inside of it and they soon start fighting because the box is very cramped.
Ash says Melvin's Exeggcute doesn't do a lot and Melvin has Exeggcute use Hypnosis on Ash. When Melvin tells the Exeggcute to stop, Not only do they obey him but Ash obeys him too. Then Melvin tells Ash to "Turn around three times and act like a Bulbasaur" which he does.Then Melvin comes up with a plan. Misty and Brock wonder why Ash is acting strange but they don't know that Ash has been hypnotized and is being controlled by Melvin. Melvin forces Ash to take him into the Leaf Forest. While Following Ash, Misty realizes that Ash is hypnotized by Exeggcute. Brock also states that since the Exeggcute belong to Melvin, he's making Ash do whatever he wants. So she and Brock run into the forest to rescue Ash.
Team Rocket sees Ash and Melvin in the forest and they decide to follow them. The forest has many Exeggutor in it and Melvin forces Ash to weaken them for him. Melvin then catches all of the Exeggutor in the forest. Team Rocket appears suddenly and they tie up Melvin. Melvin's Exeggcute starts to evolve into Exeggutor and it uses Hypnosis on Team Rocket. The other Exeggutor do the same and they end up hypnotizing each other. The Exeggutor form a mob and run to the town in a rampage.
Brock and Misty find Ash and Melvin in the forest. They untie Ash and Melvin and they wake up Ash so he isn't hypnotized any more.They all go back to the carnival and find it destroyed. The carnival owner says he planted a time bomb for the Exeggutor when they come back. Ash and his friends don't want to hurt the Exeggutor, so they try to stop them before they reach the bomb.
Ash has Squirtle use Water Gun to try and wake them up, but since the Exeggutor were part Grass-type, Water attacks didn't have very much effect. He then had Bulbasaur use Razor Leaf, but all it did was give the Exeggutor funky hairstyles. After recalling Squirtle and Bulbasaur, Ash has Charmander use Flamethrower on the Exeggutor. It stops them, but Charmander quickly gets tired. Misty tells Melvin to use flames from his wand, thought Melvin thinks it won't work. It does work and Charmander and Melvin safely send the Exeggutor back to the forest, all but Melvin's Exeggutor, who was happy to see it's trainer again. Suddenly, Charmander starts evolving into Charmeleon. Ash and his friends say good bye to Melvin and head to the next town.
