The stories follow an elderly rabbit gentleman who, urged by a kindly doctor to take more exercise, sets out in a fanciful automobile and has a series of short, episodic adventures. Along the way he meets anthropomorphic animal neighbors, including a gloomy crow and a helpful circus dog, faces minor mechanical mishaps, and lends or receives aid. Each vignette mixes light humor, simple problem-solving, and wholesome lessons about health, kindness, and staying active, presented in playful, rhythmic prose and illustrations for young readers.
