Check-out this on your game

Take a ride of mammoth then go under water with it. Then come out from water . Then you can see in your right, there comes (ready to spray)

Then you have to long press on right . The mammoth will spray water . You can stunned any flier. And you can also fill the crops with water.

' Whoever suggests taming a mammoth with 2k+ stimberries, you're an idiot'

Quote from my wife

This is completely unrelated but if you put level 9999 and taming 0.01 it would take almost 42 million stimberries

So we have Manny and Diego now we need Sid.

Knocking it out was the easy part, now I have to defend it 24/7

If you are on your own try shooting it with a trank arrow and let it follow you to a safe spot I.e your base so you can tame it safely and you are closer to all your stuff too.

I don't reccommend taming a Lv.150 with Mejoberries like I did :p

very easy to tame.

fly over to the biom they spawn in (usually snow)

get on a nearby hill or rock and kill ones you don't want as they usually spawn in 2s or 3s (recommend an argentavis). then start shooting the mammoth with tranquillisers. when it torpor runs finish it off, they are very slow so very easy to hit. (protect from dire wolves, yutiranus, etc....)

hope this helps <3

Take more tranqs than doodledex says you need, the intimidation status effect it gives you reduces the amount of torpor it takes per tranq.

Very easy to tame. They are just a bit slower than a human so you could just walk back and tranq. Run away once in a while because it does catch up while you are walking. Once your mammoth of choice is knocked just run away for 10 seconds and the rest will lose aggro. Mine just took down a low level alpha Rex and took about 1000 damage after I put 250 armour hat. It's got a good health pool anyways. It's better than the beaver in that it can defend itself and my base, it can hold much more wood. It also collects berries extremely well. Thatch is also not a problem with this. And on mobile it's water spray can knockback even a rex incase I gotta bail... Did I mention that it's faster than a rex? Only thing is that it doesn't get as much wood but in the Arctic there's plenty of wood. Just spend a few more minutes collecting wood is the solution...
