This is an entry for  shivra 's contest. Unfortunately, I don't have a scanner, so I took the picture with a camera.

So, this poor creature is a hippogryph, the unholy union of a gryphon and a unicorn. The result is a half unicorn/half-gryphon. It's never been specified which half.

I tend to think if your mother is rainbow unicorn and your father is blue gryphon then you hate life.
