Their sole purpose is to be killed for organic polymer, but you can tame and breed them for it:

Tame a whole bunch of them (you only need one male), and a dimetrodon and pelagornis.

Level the dimetrodon's melee damage a whole bunch and put it in a cage surrounded by penguins set to mating. Put the pelagornis in with them at set it to aggressive, the dimetrodon will incubate the penguin eggs and the pelagornis will immediately kill them when they hatch, free organic polymer factory.

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

+ur not the monster cuz ur tame kills them :)

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!

*puts cowboy hat on penguin* Its hiiiiiigh noot

(I laughed too hard when I did this)

So I didn’t see this on the comments but they can be very useful.

1.they can incubate eggs like dimetrodons

2.they can be used as house pets and are very cute

3.they can calm you down and easy to kill and get prime meat,they really help

Hope this tip is helpful :3

Want to know something awesome?

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.

You can carry them on any flying mount and stay warm in the snow biome if you live there or need to collect resources because of there ability to warm up its surrounding area.

Oh poor defenseless adorable little organic polymer slaves

you can use kairuku to act as mini ac to incubate fertilised eggs

Just got a fabricator but you don’t have poly and you see how expensive it is no worry these things drop organic poly and can be used exactly like normal poly except organic poly can also make you look like bushranger from fortnite
