Smallfoot

In the teaser trailer for Smallfoot, we see a man climbing up an isolated, snowy mountain. When he reaches the top, he spots a Yeti, who growls at him. The Yeti walks up to the man, who has fallen in surprise and pulls off a boot. We then realize the story is being told by a Yeti, who says the man's feet were freakishly small. He tells a group of Yeti youngsters around a campfire about this terrifying, small creature. The kids are scared, but then he reassures them the story is just a myth, and that there's no such creature.
