If you sneak up behind it, give it a mejoberry, then back straight up... over and over again... you’ll tame one. Took me forever to realize that.

I feed one of these things a single dodo kibble (on mobile) and it tamed instantly without any other factors just a heads up for those of you who don't like wasting time

Trust me, there poop will save your life, and on pvp they can unlock doors during raids

If you are going to tame these they eat berries (obviously cuz it’s a monkey)
but you need to crouch and every time you feed it you need to quickly turn around and walk away for a bit or the monkey will get scared and run away. Hope this helps

Always stay crouched while taming. And never get close enough to touch it. While following the monkey, if the monkey ever stops, its very likely It will turn and start to walk in a different direction. So be aware that it might walk in your direction. Hope this helps : )
