lol, I think it's a realllly dirty mostly white-bodied Bluebelle; a motley one, like my new one, cause I can see a little blue below her tail-hole, behind her symbols!
If she is a partly-white one, could you post some pics of her once she's cleaned up? lol, I love the varied weird white/part white Bluebelles, I want to do a sight about them, but there really isn't any info on them, other then it seams like they are all origanally from the western states of the US.
