They can ride in your shoulder. Having a monkey while sailing in your pirate ship is strangely satisfying. 😎

If you put them on wandering they'll pick up berries. When you put it on your shoulder it throws poop at your enemy and the poop does damage and slows down the target

If you put stuff in its inventory like eggs or materials and then put it on your shoulder it will weigh less than it would with the items in your own inventory making it perfect to cook kibble fast

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 : )

This creature may seem frail and weak but once you tame it you will release that it has access to the most powerful weapon on ark THE POOP CANNON

Have troubles of disconnecting and dying and not being able to find your loot? Tame a high level with tons of health and place and tracker on it. It should remain by your body.

The mesopithecus is able to open doors when there locked when attacking the door or trying to escape from the inside out

How to rule the sea:
Step 1. Tame Monkey

Step 3: Put Cloth Hat on said Monkey
Step 4: Sail the seas with your pirate monkey.
Congrats u r now pirate.

Put arrows in it, he throws them along with the poop!

You can place helmets on it too. I place my mining helmet on my monkey and use it as a source of light at my base. But you cannot see the light if the monkey is on your shoulder and your looking in first person. You can see the light in the orbital camera, While riding on another Dino in 3rd person, and when the monkey is on another persons sholder or on the ground. Hopes this comes in handy : )

Good for Pvp severs if you can tame high level preferable 100+ as they can unlock doors from entering a open window

Shoulder turret. If you wistle aggressive, neutral, or attacking target while they are on your shoulder, they will throw poop at your target.

Cover a tamed one in c4, set it to agressive, and hurl that hoe into your neighbor's yard.

Despite what others have said, they do NOT throw arrows.

They will throw poop at enemies (I'm serious) Also you can put hats or helmets on them.

Try to practice with berries before wasting kibble

Can find them in the beaches! You can not knock them out. You need to follow behind it and feed it kibble or berrys

Put one on your shoulder and whistle aggressive in caves, it lets you know if something spawned behind you with its alarm.

They're fun to have around, they unlock doors. I dunno, don't ask me, maybe they have a monkey wrench xD. Anyways they are good to have on your shoulder on neutral as they throw poop at enemies when you are hit, which slows them down. Good for taming things like trikes, just keep whistling neutral, passive so they don't absolutely hammer the thing your trying to tame

Give berries.
Wait a bit.
Repeat.
Boom. You got a poop flinging cannon
