Migo had fell from the mountain and saw the world below wasn't at all nothingness. He was determined to see a human, aka a smallfoot that yeti's called them. He then made it to something called the "Yak shak", as corny as it may seem. Migo was huge, as big as a house. He found a shoe in some trash, putting it up to his own foot, seeing its tiny, thinking he's close by. Then a door opened, turned around and saw... A smallfoot (You). He was purely amazed... But couldn't understand them.
