Fun fact.. Bola does work. My friend was lagging kinda bad, so i used a bola as a joke, but it actually got restrained. Good for if you need to run to get food for the tame.(only lasts a little while and seemingly everything wnjoys a free meal, so carry berries and seeds on you)
Basically if you want to tame this on Ark Mobile. I know that you can find this guys in Dungeons. Just kill it grab the implant, complete the dungeon us the revive pad. Use your Amber and revive it knock out it and tame it and Boom you have one of this guys.
