Osgood is one lucky and curious little kangaroo-like animal. This unique critter inhabits America's grasslands, hopping on back legs, stuffing plant food into cheek pouches, and is only the size of a kid's fist. As a young kangaroo rat, he faces adventures and challenges when he leaves the family nest. He must quickly learn about the complex web of many night creatures outside. From the small but deadly grasshopper mouse to the strong and cunning coyote, Osgood and his family encounter surprises from these and other nocturnal (night) animals. Over time Osgood hones his survival skills since he is a night dweller too.
