Ash meets up with Bianca who has been sent by Professor Juniper to deliver a Badge Case to Ash, however it is very dirty. Just as Ash puts his Trio Badge in the case, it gets stolen by the Chinchilla Pokémon, Minccino who is trying to clean it. Bianca, who wants to catch a Minccino, sends out her Pignite, the evolved form of Tepig, but it is able to dodge the Fire Pig's attacks and use a Hyper Voice to knock it out. Ash then sends out Oshawott to battle the Minccino, but Minccino easily defeats Oshawott with its Sweep Slap attacks and it escapes. They decide to set up a trap with a dirty spoon and Ash tries to use his Snivy to immobilize it with Attract, but the Minccino also knows Attract and Snivy is enamored instead. Ash sends out Pikachu who manages to weaken the Minccino with an electric attack. Bianca decides to take out a dirty Poké Ball, enticing Minccino to clean it and accidentally get captured. With Minccino under control, Ash gets his Badge Case back. After getting to a Pokémon Center to check up on the Egg he received previously, Bianca challenges Ash to a battle. Pignite is defeated by Pikachu in the match, but Bianca says that she will get better for their next battle.
