LOL.
Unicorns are real. Of course the made-up Hollywood unicorns, where beautiful = good and ugly = evil , are not real just like Garfield, Mario, Mickey Mouse, Santa, Zelda, etc, as they are not meant to be real.
This is one place where those who wrote KJV didn't use the best word in their translation . It's should have been rhino instead of unicorn since a unicorn by definition has only one horn. It's even speak about one horn will be greater than the other (ten thousands of Ephraim vs thousands of Manasseh) just like you find on a rhino. No big deal since at that time they understood a unicorn to be a rhino.
