Doctor Dolittle is a world-renowned veterinarian who speaks a wide array of animal languages. He sets off from his home in Puddleby-on-the-Marsh, England, in search of the Great Pink Sea Snail. In so doing, he and his friends meet such exotic creatures as the Pushme-Pullyu and the Giant Lunar Moth. This musical is the source of the hit song, "If I Could Talk To The Animals."
