With a post-1900 POD, have there be either so many wild penguins in the Arctic or so many wild polar bears in the Antarctic that polar bears hunting penguins is a common sight in either Pole.
Would it be able to survive European contact as an independent kingdom, or at least have a mostly native population and a surviving monarchy like Tonga does?
I.e.
They use iron
They have organized and densely populated kingdoms instead of the chiefdoms/tribes they had irl
They have multiple cities comparable in size to largeish European cities, like Benin or Timbuktu in Africa (Cahokia was the only real city they had irl)
