It's a horse with a bad hip who needs a walker.
Unfortunately, the only way to get this figure is in a 3 pack with 2 figures I don't care about. But yesterday I found one in the wave 8 Neon Pony blind pack box so I figured, why not. I'm pretending that the coloring is due to her being an irradiated horse who is using a walker. Because I've read comic books an have come to understand that radiation = magic.
