We all know that Santa Claus is making a list and checking it twice... but you won't find precocious provocateur Moon Girl on the nice list this year! So when the children of Yancy Street need some holiday cheer, why is it up to notorious grinch Lunella Lafayette and jolly red Devil Dinosaur to fill in for Saint Nick? Then, eight hours of sleep usually means a full night's rest - but for Lunella and Devil, it means a fierce fight to stay out of the Dream Dimension! Welcome to a place at the edge of our subconscious minds, where all manner of monsters dwell - but who is the Dream Dimension's newest resident? And what does their appearance mean for the nocturnal adventures of Moon Girl and Devil Dinosaur?

Collects Moon Girl and Devil Dinosaur #37-41.
