Are not affected by oxygen while on your shoulder, so it helps you to find your body if you die because it will be flying right above the water where you died. Also if attacks while on your shoulder, so it can collect bodies for your herbivores, help keep attackers off of you, and can be thrown at Dinos do kill them. There is no reason not to carry one, they are very helpful.
I tamed a lvl 15 female one and named it Nova and she was really good. She killed a whole pack of lvl 20 carbonemys without taking any damage and I didn’t do anything except stand there and watch in shock and awe. This is a MUST tame for everyone who reads this. I was only lvl 10 at the time I tamed it and now I’m lvl 40 and this creature has never failed to impress me.
It you put them on aggressive and perch em on your shoulder, they warn you of any danger with a scream. Usually it’s a diplo or a compy. If it weren’t for my dimo I would’ve died hundreds of times, he once yelled so I left and the next day i went back and say a giga killing a pack of raptors.
These little guys, tame no less than 15, the more the merrier, I'm at 30 currently. I don't use them often because ut feels like im cheating. LOLOL They shred through Alpha Raptors and Alpha Carno but they're all 2nd gen at least for the imprint bonus. I level HP Dmg and movespeed to 115% minimum.
Tame every one of these you see regardless of level. Up only melee and maybe some health. Once you have 20-30 whistle for them to follow you and attack your target. Hit a rex, bronto, or literally anything that can die once and watch as your hurricane of teeth tears it apart.
Pair a pack of these with a bunch of dilos and you got yourself both land and air superior. You can also bring these with you when you’re riding your Pteranodon on exploration, they will save you and your Pteranodon’s ass when you need to land to regain stamina. They basically dilo but on the sky.
