I like MLP:FiM, don't get me wrong, but having ponies, even if you made them real horses instead of cutesy, MLP ponies, it would still feel wrong. When I think of Feral, I normally think of carnivores of some form.. a horse just doesn't fit the feral image to me. I dunno. Plus, there would be so much rainbow and love and holy - I would die from just that. Seriously, we're already cursed with Sparkle Dogs, we do NOT need Rainbow Dash and Pinkie Pie running around everywhere. No thanks. xD
