Collects Moon Girl and Devil Dinosaur #37-47. Bad dreams and great team-ups! Moon Girl and Devil Dinosaur must fight to stay out of the Dream Dimension, a place at the edge of our subconscious where all manner of monster's dwell! What fearsome fiends lurk within the mind of a 65-million-year-old thunder lizard - or worse yet, a 9-year-old super-genius?! Doctor Strange and Sleepwalker are about to find out! Then Lunella meets the original kid super hero, Spider-Man! And if that isn't amazing enough, wait until the War of the Realms breaks out - and our heroes share a mythical adventure in Asgard! Next, the Lafayettes face a family crisis that threatens time and space! And - at last - it's the battle of the biggest brains in the Marvel Universe...and it will be fantastic! Is Reed Richards smarter than a fourth-grader?
