This is Chamomile Amethyst, one of the first fat pokémon I've ever drawn in my life. I originally sketched her and then scanned and inked and stuff. She'll be having smaller boobs soon (sorry!) and she has a sports bra now, but otherwise she's the same big girl.
Catch her alongside a couple other big mons at my ask blog, http://ask-three-spookefats.tumblr.com in October and http://ask-three-pokefats.tumblr.com the rest of the year!
