THE STORY: Six-year-old Nicholas gets into hot water when he invents a non-existent creature called Dogbrain to blame for his bad behavior. When Dogbrain materializes (visible only to Nicholas) and wreaks havoc on his family, Nick and his little brother are forced into the night-time streets of the city where they encounter a huge dog, a bag person, and finally, a rescuer, straight out of Nicholas’ imagination—the same imagination that conjured up his dark side as the creature Dogbrain. Thus does Nicholas learn how he has within him bad and good, and the power to keep them under his own control.
