Dr. Melvyn P. Otter is the GP for a small group of animals. He lives in a delightful riverside house with his wife, Raylee and his faithful assistant, Flybread (a cat). Each episode, Dr. Otter is called upon to tend his little catchment area, which include Mrs. Canny Body, Dunston the mole and the Rabbit family, as well as a chameleon called Lucky who comes from Spain.
