通称：远古企鹅
物种：远古企鹅种
时代：古新世晚期
食性：食鱼
性情：友善
野生
远古企鹅是一种极其温顺友好的生物，除了对待鱼类以外。说实话，我不太清楚远古企鹅如何在岛上的寒冷气候下生存，因为有很多捕食者在这些冻土上游荡。 远古企鹅很弱小，并且它只有一种防御能力：一种悬浮在脂肪上，可以被当做轻型护甲的细小密集粒子。 更雪上加霜的是，一位聪明的幸存者发现提炼远古企鹅的脂肪（里面浓缩了粒子），可以生成一种在高级部落生产过程中使用的聚合物相同的物质。这导致许多部落会大量的捕猎远古企鹅，这种行动俗称“远古企鹅俱乐部”。
家养
远古企鹅对于战斗没有任何帮助，因此没有理由驯化它去战斗。但远古企鹅仍因为它们的可爱和友好的个性，以及它们身体产生的极端热量被驯养。仅仅站在远古企鹅旁边就可以给生存者在冰山上漫长严酷的夜晚里保暖。
Common name: Kairuku
Species: Kairuku waitaki
Time: Late Paleogene
Diet: Piscivore
Temperament: Friendly
Wild
Kairuku waitaki is an amazingly docile and friendly creature, to everything but fish. Honestly, I'm not quite sure how Kairuku manages to stay populated across the Island's colder climes, with the many predators stalking these frozen lands. It is weak, and has only one small defensive trait: suspended in Kairuku blubber are small, dense particles that act as a light form of armor. Adding to Kairuku's problems, a clever survivor discovered that refining Kairuku blubber (concentrating the particles in it) can yield a natural form of the same Polymer utilized in advanced tribes' manufacturing processes. This has caused many tribes to hunt Kairuku extensively, a practice colloquially known as "Kairu Clubbing."
Domesticated
There is no reason to tame Kairuku for combat, since they are useless at it. Still, Kairuku are regularly tamed for their cuteness and friendly nature, and the fact that their bodies run extremely hot. Just standing near Kairuku can help keep a survivor stay warm through long, harsh nights on the icebergs.
