Make a taming pen. Put mejo berries in your last slot and let the pega steal it. After it steals the berries use a whip to take it out of its hands and it will steal from you sooner. Only way to tame a 150 it seems since its taming bar goes down while it holds the berries.
literally bought console ark after playing mobile ark for ages, this little sh it came and robbed me of my tranq arrows, then, had the audacity to come and tame itself on me after taking my 20 mejoberries, didn’t want this pet but I took it home, died 20 seconds later to a bird that picked it up and ate it, still don’t know why or how but I also don’t care
