"Monsters are loud. And rude. They like to smash things and they always need to be right. But not Yeti. Yeti bakes banana bread and sings to whales and always has a nice word to say. But sometimes you find yourself alone when you're different. And Yeti doesn't know there's a special surprise in store for him"--

Unicorn and Yeti run into each other (literally) while looking for sparkly things, and despite some differences, (for instance Unicorn is magic, Yeti is not, Yeti likes snowball fights, Unicorn can not throw snowballs)--the two become friends over a shared love of hot chocolate with rainbow sprinkles.
