This is a skin i made for the Mine Little Pony mod (which i love) and i have 2 ways to set it:

1. Set it as your skin online.

2. If you play offline alot you can do it my way by opening your minecraft.jar install the mod (if not installed) and go in the mob folder (This works for me im not sure if it will work for any one else) delete bpony_5 take the skin and name it bpony_5 and put it in there.

If it doesn't work for anyone just put it in the comments. And add diamonds if you like it!
