So my first attempt to tame one of these in a new server. So I was walking alone a beach when I spotted a beautiful white one (it was not a unicorn), I got 15 carrots when I saw it was only level 1. Then I attempted to tame it. It ate all of my carrots and then bucked me off. So then I got 20 carrots and tried again. In the end it ate 30 carrots and 22 mejoberrys (sorry for typo) and it still would not tame. In the end I left after wasting about an hour trying to tame a level 1 horse.
