I just found one at 4:21 am. The adrenaline was so bad lol. On mobile, the taming process isn’t anywhere near what you do for the equss. you don’t ride it. Or feed it any crops. I found that out when i tried to tame mine. It only takes griffin kibble. Good Luck!
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
