Would you rather live in a world where Santa is real (except he's an evil warlord who rules most of the northern hemisphere with his elves) or a world where Yetis have come out of hiding and declared war on humanity?
How many yetis?
Roughly 10 million Yetis live in Tibet. There are also about 1 million Yetis living in the North Pole and a million Yetis living in the South Pole. The Yetis are allied with their relatives the Sasquatches. The Sasquatches number in at least 5 million, with most of them residing deep within Northern Europe, Russia, the Alaskan/Canadian wilderness, and the swamps of Florida. Thousands more are dispersed along the Appalachian Mountains and the Rocky Mountains. It is unknown how they remained in hiding for so long. However, they are much stronger, more agile, and more aggressive than humans. Their intelligence is slightly lower, but some Yetis and Sasquatches are as smart as humans.
how can a yeti survive in a tropical humid swamp?
Not the Yetis, the Sasquatches.
Can they use firearms? Or do they just claw you to death?
Imagine a Planet of the Apes scenario without the deadly pandemic.
Keep in mind that some places will be completely devoid of the Yetis or Sasquatches while others have an abundance of them.
Evil Santa. Would he still wear red or would he wear black?
His clothes are dyed by the blood of those on the naughty list.
