It's because she's a really colorful fox thing with long ears (nobody really knows what she is) and she has rainbow color fur. Everyone is envious of her because she's so pretty, so she ended up having no friends and she feels ashamed of her body. So she decided to cover her fur with black paint (hence the dripping color).
It's a sad story, but she got over herself and is happy now

Fellow EXOtics will know what I mean. Faving everything on my ipod is too slow, so i shall favorite everything at a later time. BUT REALLY. DEVIANTART NEEDS A "FAVORITE EVERYTHING" BUTTON. For awe-striking galleries such as yours!
