Look, I like all of these ideas but,
1. You can make a fox with the canine creator.
2. Deer and bears will come out in Aro'Kai.
3. You could make an Eagle from Aro'Kai's Owl creator.
4. "Feral"=Horses (not really now although dogs are the same way, used to be very feral, now almost all domesticated). Besides, like Jeanette's point. And all the MLP bronies will have something they can make their character of. And a lot more horse-lovers would come to FH, too. Since Aro'Kai wouldn't be planning on it. And, making a horse out of a deer wouldn't even look good (in my opinion).
And this game was based off of IT. So what? We can't just keep with the same boring (no offense) models. I am sure we can add at least ONE new, popular model that most people will like, and that will bring more people.
