A Nightmare on Mushroom Street

A dark secret dug from Mario and friends' past threatens to be unleashed when a series of strange events begin to unwind: the emergence of a tall disfigured Koopa that stalks them; his presence only seen in their dreams. After one of them dies violently, the rest realize that what happens in their dreams is real, and the only way to stay alive is to stay awake . . .
