Kassy is here to tell you a story. Frame by frame. Her subjects are two frozen girls. They are frozen all the way in the video. Kassy poses them first to give you a general idea of how they are and what they can do. Then she makes a short story starring our unlikely heroins. She narrates the story while she puts the two frozen girls in certain stages of the story like you would see it in the panels of a comic.
She changes their poses as well as their facial expressions by hand.
