I just googled her. My monitor exploded with color, lol.
Well, the colors in your deviation make sense, though lol
I mean, at first, pink ponies may seem kinda odd, but then consider 1), the big eyes, forehead, bifocal vision (eyes pointed forward instead of sideways), and other anatomic traits aren't pony either (like how pinkie slept in a ball, then scratched her ear like a dog), so really, we can safely say they're not Earthly equines. 2) Once you've covered that part, realize animals come in all kinds of colors...
Yeah... I kinda did just imply they're aliens and not ponies, btw, lol. but I am an aspiring sci fi writer, so... But whatever they are, they're not ponies as we know them on Earth lol.
I originally started watching MLP as something I could get my daughter into when she got old enough (Prescreening is something every parent should do IMHO) And I wound up really liking it. The characters are endearing, the show is funny, and it's over all just an enjoyable 22 minutes. If you haven't seen it I would recommend you giving it a chance. It'll grow on you like a fungus.
