Mustache Unicorn 

The best breed of unicorn. Many people adore Mustache Unicorns due to their fancy appearance and disposition. Unlike normal unicorns the Mustache Unicorn loves top hats and fancy monocles. And what is a Mustache Unicorn without a Mustache? Mustache Unicorn's no matter female or male have brilliantly groomed Mustaches that vary in color, shape, style, and size.

My pet Mustache Unicorn dose not go outside without their golden monocle.
