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.
When I first started the game, I found one of these beauties. I immediately tamed it as fast as I could, and once he was tamed, I saw a fire in its eyes. I named him Steven. Steven has always been there for me. He gathers stuff for me, helps me kill and fend off creatures from my base, and has had a family with his wife Theresa. He now has three Children, Larry, Kevin, and Carmen. I tamed Steven when he was only a level 4, and I was a level 8. I’m so glad to have found him and we can grow old together. I’m now level 57 and He’s level 68. We’ve had a great life together.
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!
