IL025: Primeape Goes Bananas

Synopsis
Ash contacts Professor Oak to let him know that he now has four badges. Oak tells Ash that all his other rivals already have five. Just as Ash is making plans to go to Celadon City, they encounter a Mankey. Brock gives Mankey a donut to eat and just as they are watching Mankey eat the donut, Ash throws a Pokéball at Mankey. Ash gets it back to find he has caught the donut. Mankey starts chasing them. Brock tries to distract it with another donut, but it doesn’t work. Eventually, Mankey steals Ash’s hat which was an official Pokémon League hat. Ash tries to get it back and fails. Team Rocket arrive to get Pikachu as usual and Mankey walks by, James kicks it away and it evolves into Primeape. Primeape chases them for a long time until Ash finally catches it. Primeape attacks Team Rocket and they blast off again. Ash and friends discover that Primeape chased them all the way to Celadon City. Meanwhile, Team Rocket land in a field full of Primeape who all attack them.

Trivia
