Whitney takes our heroes to her uncle's Miltank farm in the outskirts of Goldenrod City. Here they sample the finest in Miltank dairy products and learn how to groom and care for these Pokémon. Ash realizes this is a great opportunity to study Miltank first-hand and hopes it will help him against Whitney's Miltank in their next battle. After learning about Miltank and coming out victorious in a battle against Team Rocket, Ash realizes the answer to overcoming Whitney's strongest Pokémon is good old-fashioned team-work.
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.
