You left your house and just returned and as soon as you enter you see a 3ft tall rattata eating some BFC and that rattata is very fat it's probably 250 pounds which is alot for a small pokemon.

Rattata: Huh? Oh you came home sooner than I thought...I though I could escape before you got back...laughs nervously

This rattata was surprisingly thicc for a boy probably because it's obese
