This creature acts like a hot hands once tamed. For example, if you're in the cold weather and you have no fire but you have a penguin then it will warm you so you're less cold. The more penguins the more insulation.
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.
