Well, Then put in Shadow_Spark.
I'd take care of mare 1, 3 or 5.
(And yes I know that 3 is my sister!)
Spark is an unicorn Surgeon. He is a passionately lover, who also likes to use Magic to please his mare. :3
He is a mostly friendly unicorn who likes to have fun with his friend and a general funny live. His friends can count on him a hundret percent.
