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. Please press the good button for some respect for me.

' 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.

King

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
