I see quite a few options that give the characters "human" skin tones, human eyes, human noses. I'd like to have maybe one or two "human" looking ears. I'll even take gorilla, monkey, or chimp type ears. Some have already suggested tails, and I think it would be cool to have that option (or not!) if someone wanted.
Maybe even wings too if you ever add bird or bug character parts.
Also, I'd like to be able to donate to pockieland. I really don't need to "buy" anything from the in-app purchase selections but I would LOVE to donate to be able to push for other things like the farm, more mini-games (maybe mini games to do while a character goes to "work" ?), the programming it will take to make human ears, stuff like that. :)
