I thought I would share this born in-game unicorn foal! I have not altered him in any way! Poor little guy needs a good home!
I named him Cesar; his traits are Brave, Untrained and Clueless; and as you may have surmised, he's a male! :P As always, feel free to alter to suit your needs/wants/tastes! :P

Adding a shot of the little guy with his father outdoors! The mother was a wild horse that I released back to the wild! Forgot to get a shot of her! :P
