In "Dr. Dolittle 2," a desperate group of beavers seeks the help of the animal-speaking doctor to protect their home from encroaching loggers. The key to saving the forest lies in preserving it for a rare bear, but there's a catch: she’s the last of her kind and cannot reproduce. Undeterred, Dr. Dolittle enlists the aid of a circus bear, embarking on a mission to teach him the survival skills of the wild, as well as the art of wooing female bears, to ensure the future of the endangered species.
