Wow! Thanks ABrownCrayon. Huge mystery solved.
.. shameless plug, but if you're thinking about selling her I'm totally game. =D
Lol! Sorry. Tunefull is taking a place in my sister's herd.
Thanks for the image Moonstone. I can totally see why not many people have noticed. My sister and I didn't even notice the differance when we bought her, and it was just a fluke when we were comparing our Tunefulls when we noticed the hair colour.
Thanks everyone for all the help & info.
