Neptune (Guests of King Neptune)


 * For the planet of the same name, see Neptune.

Neptune was king of Earth's oceans. He and his mermaid servants lived in a castle made of sand located on a South Seas island. After sending a wave to move the Doctor, John and Gillian out of the way of a volcanic eruption, he provided them with a great feast. Before they left, he gave a pearl necklace to Gillian and a golden shell to John. (TVC: Guests of King Neptune)
