The unicorn is the national animal of which country?

There’s no point to national animals, flowers, or any other arbitrary symbols that never get used for anything. So why not have some fun with it? 

A bald eagle is cool, but what if we changed it to, say, a dragon? Who would want to mess with a country if they suspected even a tiny bit we might have a dragon? No one, that’s who.

The unicorn isn’t quite as intimidating as a dragon, but at least shows some backbone. That, or this country somehow showed up late on National Animal Picking Day and saw that the only things left were a duck, newt, or possum so just wrote in “unicorn.” 

Whatever the reason is, I respect it. A unicorn is second only to a pegasus in my eyes for ways to make a horse cooler, but no country as far as I know has that as its animal. Instead, I’m more than happy to settle knowing that this country isn’t satisfied with any real animals representing it. 

Which country made this mythical creature one of its national symbols?
