Plot
Mash wants a Pokémon of her own, but her parents, Ash and Misty, say she's too young to have one. An argument ensues which ends with them punishing Mash. Upset, Mash decides to run away and get a Pokémon herself.

She goes to Professor Oak's and asks for a Pokémon. When Oak tells her she has to be at least 10 years old to have one, Mash shows her an ID to prove otherwise. When Oak isn't fooled, Mash steals a couple of Pokémon and goes back home to her parents. She tells her parents that she got lost, avoiding discussing what she had actually done.

When Mash is asleep, one of the Pokémon under her bed, Wailmer evolves into Wailord, causing the entire house to break, revealing the truth to her parents.
