Put a male in middle, at least three females surrounding it, put sloped ramps so fermented eggs fall down. Put something that has good weight reduction and or good farming for organic polymer, it will kill babies
Tame a bunch and make a penguin farm for poly. Nine females to one male works great. Set up a bunch of ACs and have them on wander when the babies hatch club them. Free poly within the comfort of your own base!
A swarm of these in the water teams up AMAZINGLY with a Baryonyx! Use the stun attack on Alpha Sharks or Alpha Carno and watch as your team of Tuxedo hitmen nips them into a surprised-looking skeleton. Its hilarious.
-Once tamed the Kairuku acts as a mobile heater. It adds 35 to your hypothermic insulation (your how cold you are stat) the more Kairuku you have compounds their effectiveness.( the further away from the penguin the less effective it is)
-Can be used for breeding so you don't have to waste mats on Air Conditioners
