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)

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.

The babies taste best

They make perfect kitchen assistants, I promise. Make you feel all warm and cozy.

Put them in you house if it's cold. If properly spaced out, they can keep you warm in the frozen biomes.

-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

Use a pelagornis to gather their dead bodies. You will get more organic polymer.

If you play Prim+ they work great in replacing the A.C's I have found 6-8 work wonders for hatching eggs!

Make fertile eggs and stick them in refridgerator,in there they will last 800 days so you can stock 48 per fridge. Then just hatch when you need polymer.

Arks nauteral torpedo have c4 on it then make it go toward a enemy raft and boom (put all points in speed)

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.

In the middle of a fierce war against the dodo and the lystro for cutest ARK creature, the kairuku, or penguin is a pretty cool dude xD. They work as mini heaters, which is great for the cold north, or just the cold nights. They are probably the best snuggle buddies, cuz they're so warm. Also you can put ANY helmet on them, to make them super cute. Penguin fashion show anyone? Oh yeah, an army of these things also makes for some epic underwater battles, they're like little torpedos! They are very cumbersome on land, but underwater they are like dimorphodon, kinda.

Most enjoyable way to get polymer - use a chainsaw, nuff said

Kill them to get organic polymer, which can be used as regular polymer

Have a bunch of females with a couple of males on wander, use a moschops on attack my target, it will collect dead babies that die of you don't claim them. Free polymer

If you want to be an absolute monster, make a breeding pen and club the babies.

Embrace your inner Canadian and club these poor guys for a ton of organic polymer. Or use a pelagornis. Your choice.

Similar to Dodo birds, the Kairuku can be used to get a decent supply of eggs over time.

Using these for hatching eggs is a bit impractical as you need about 18 to cover most eggs.
