I dont know how many of these I have tamed and I thought it was a stupid small Easter egg, but no they are amazing do not just get it killed like I once did multiple times. They help get twins and triplets and their poop is fun.
Found a low level of these guys at the red peak, BESIDE AN ALLOSAURUS PACK IN MOBILE! Had no plan of taming it though, so I left it with the pack. For some reason it outran the allosaurus pack. I’m stunned. What if these things could fly too? Then it would one of the ultimate mounts then. P.S. It was just level 2.
I encountered one on Ragnarok, freaked out tamed it and was happily riding it back to my base when a stupid Raptor decided "I'm about to ruin this man's career" and killed my Unicorn. I have yet to find another one and I have a gravestone for my lost Charlie.
If it won’t allow you to feed it, knock it out and let it wake up then try again. Most likely due to the fact someone else tried to tame it before. Also, it tells you when to feed it at the bottom corner of your screen. PLEASE UP THIS
