it may be brutal but if you're trying to get organic polymer and you kill one of these in one hit, the other kairukus won't panic and run away. they only run away if you hurt one and it doesn't die. same goes for dodos
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.
1 go to the island in the top left corner in the island map 2 find one 3 shoot in the head with crossbow 4 whack the stuffing out of them with a club to get organic polymer 5 get out of there before something kills you.
