The Voyages of Doctor Dolittle

The Voyages of Doctor Dolittle is a high-seas adventure of exploration, shipwreck, derring-do, and of course, talking animals.
The animals talk because Doctor Dolittle is no ordinary doctor. He has learned the secret of animal language, and uses his talents to help out his friends in the animal world. Now nine-year-old Tommy Stubbins, the son of a shoemaker, has the opportunity to become Dolittle's assistant, and join him on his journeys. Together with their animal companions they will travel to the strange Spidermonkey Island and beyond, in search of a colleague who has gone missing.
The second of Hugh Lofting's Doctor Dolittle series, The Voyages of Doctor Dolittle was awarded the prestigious Newbery Medal for children's fiction.
