The best way to tame this creature is by wearing fur armor and heading to the Arctic and knocking it out there I have brought plenty back to my base and the continuously die because they won't knock out taming in he Arctic seems to be the only way to do so that I have come across
They are so cute! I tamed one today and I named it Karri. She is a juvenile and very weak but still cute. If you kill baby or juvenile kairukus on purpose. I will find and burn your base in multiplayer.
I use a cross bow its almost 50/50 chance it will kill it but if that happens you can just pick out a different kairuku, and feed it raw fish and/or raw meat to tame they are very easy to tame almost dodo like in a way
