A gift for my good friend: https://www.furaffinity.net/user/wingal/

Its of the time he turned my little pokesona into a easter egg pokemon through a lot of stuffing...Turns out chocolate makes Furrets gassy though.

EDIT: Had a brilliant little idea after showing this to someone...Retcon! It's a new evolution for the Furret line. You feed a Furret chocolate pokepuffs non stop for an hour and it evolves into a Furregg. Furreggs have very low attack but a huge level of HP and physical defence, being a poison/normal type. Instead of physical damage it has a assortment of moves to sufficate...I mean, 'poison' enemy pokemon over a long period of time as it bounces off attacks like a balloon. Maybe even some attacks right back.

EDIT 2: Ok I'm taking this a bit far but...STATS!!!
