On the way to Veilstone City, Brock brings the group to the Mountain Hut Maid Café where they meet the owners, sisters Spring, Summer, and Autumn. The sisters show them how they produce the milk, which is where they learn that Autumn's Miltank, Ilta, does not like to listen. Brock agrees to help Autumn and Ilta, so Ash and Dawn decide to help Spring and Summer with the café in their absence. Brock then bestows all his breeding knowledge to help Autumn and Ilta get along and cooperate. Meanwhile, Team Rocket try to have their own café, but when that fails they decide to steal Ilta instead.
A young boy named Ash Ketchum embarks on a journey to become a "Pokemon Master" with his first Pokemon, Pikachu. Joining him on his travels are Brock, a girl-obsessed Rock Pokemon Trainer, and Misty, a tomboyish Water Pokemon Trainer who may have a crush on him. Ash and Co. end up traveling through various regions, including Kanto, the Orange Islands, and Johto, and then enter the Pokemon League competitions there.
Along the way, they run into many confrontations with Jessie, James, and Meowth, a trio of Pokemon thieves who are apart of an evil organization called "Team Rocket". But every time Team Rocket try to do their evil deeds, they fail thanks to Ash and his Pokemon.
