On their way to Celadon City, our heroes encounter Mankey, a wild Pokemon that if rubbed the wrong way can go into uncontrollable fits. Not realizing its unpredictability, the party accidentally upsets Mankey. To make matters worse, Team Rocket arrives and an all out war is waged by Mankey, who evolves into a ferocious Primeape, against anyone in its path. Will Ash be able to add Mankey/Primeape to his ever growing collection of Pokemon without having to withstand Primeape’s unrelenting wrath?
