I found a green one in the middle of the redwood- Is that odd? (I’m on mobile)

Yes they do spawn on Lost Island. Go to 40.2/43.2 and you will find some of these little guys & gals.

Logged on and saw my tames were killed by a kairuku..How?!?!

Looking for a good Fjordur spawn? The NE coast of the SW part of the map is home to many of these not so innocent waddlers. Hope this helps!

Put one in your house and get oil fast

Grab Lucille and hit Glenn as hard as possible as many times as possible to collect organic polymer.

For the person on mobile who found one in redwoods, ha! I'm not sure if that's odd or not but mobile happens to generate some really weird creature placements. I found a procoptodon in the middle of the arctic and my sister found a Griffin in the Arctic. We both play on mobile.

Kairuku are found in the coldest parts of the map, you'll want fur clothing to keep you from freezing to death.

Does anyone know if these spawn on lost island?

Once killed, use a club on the penguin to collect organic polymer
