Pearls are a Spoink's Best Friend

Continuing the trek to Fortree City, Ash and the gang come across a Spoink, a Psychic-Type Pokemon. However, this Spoink is upset after losing the Pearl it keeps on top of it's head. After Spoink tries putting a couple of round Pokemon on it's head (including an Igglybuff and a Voltorb), the Pearl is found, however Team Rocket, working with renewed vigor after Giovanni threatened to replace them, steal the Pearl. After coming across a fair, James is approached by the same Magikarp Salesman who has made his life a misery in the past and offers to trade Feebas for the Pearl. After discovering Feebas evolves into Milotic, the most beautiful of Pokemon, Jessie, James and Meowth eagerly agree. However, when they let their new Feebas have a swim in a nearby river, they discovered the Feebas is just a Magikarp painted with a Feebas colors, meaning they have been swindled yet again (when will they learn?)! After Ash and the others hear what's happened, they realise that, in order to get Spoink's Pearl back, they need to find the Magikarp Salesman before Team Rocket do!
