The Man in the Moon (MiM) has a bit of a problem. Most nights, the moonbeams he sends to the earth help keep the nightmares of children at bay. But what if it's foggy or cloudy out, or if there's a new moon and the moon doesn't shine? It's obvious he needs some help, and he's found what seems like the perfect assistant: a sleepy little man named Sanderson Mansnoozie, Sandy to his friends, who specializes in sweet dreams. Will MiM be able to wake Sandy up and convince him to join the fight against the Nightmare King?
