While treating the animals on the island, Dolittle receives a surprise patient – the Great Pink Sea Snail, which has also caught a severe cold. Dolittle discovers that the snail's shell is watertight and can carry passengers. Dolittle sends Matthew, Tommy, Emma, Polynesia, Chee-Chee, and Jip back to England with the snail. Emma wishes to stay on the island with him, but the Doctor is adamant that a relationship would never work. She finally admits her feelings for the Doctor, and kisses him goodbye. Dolittle cannot go back because he is still a wanted man. Furthermore, he wishes to investigate the natives' stories of another creature, the Giant Luna Moth. After his friends have left, Dolittle realizes painfully that he has feelings for Emma.
