once, i was out killing rexs and brontos for xp around some river in the southern islets area, don't remember exactly where, and i had seen a few equus roaming around accidentally getting themselves killed. i was trying to protect the horses and kill any rexs and allosaurus and raptors that were attacking them, and i saw a rex chasing one that looked like it was pure white. i've never seen a unicorn before, but after hitting the rex a few times i realized "wait a minute, equus always have stripes.." and i got really excited. then, right before i killed the rex, it killed, and ate, the possible unicorn. .. i was really upset.
