As a young boy and girl struggle with the idea of having to go to sleep, they get interrupted by the moon who questions their desire to stay up. The moon tells them that by going to sleep they will get to do lots of fun things, such as saving the world from a gang of nose-picking space zombies, or drinking from a cream-soda flavored river and riding in air bubbles from a pink underwater elephant. However, before the moon can finish, he notices their dreaming adventures have already begun.
