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.

Quote from my wife

So we have Manny and Diego now we need Sid.

(mobile) best way to tame is using vegetable with sppthing palm most easy way to get it is hunters cave. Just bring a 2x2 stone trap almost 100 trank arrows on crossboss 8-10 spike walls and about 50 or 60 carrots 1 soothing palm and make sure you have a good armor or a weapon to fend of hostile and place your trap on a good spot to protect ,the difficult part is to find a lvl300 and luring it . Make sure you have a flyer though PT is good. Goodluck

Hope this works for you.

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.
