Doctor Snuggles was travelling home across the sea in Rickety Rick the Shed. "What's that dreadful moaning noise?" said the Doctor. "It sounds like an enormous foghorn."

In a few moments, Rickety Rick came to some rocks with the waves splashing all round them, A strange looking man dressed in a cloak made of seaweed was sitting on the rocks, yawning.

The man had a crown on his head and a three-pointed spear in his hand. His yawns sounded like a foghorn! "I am King Neptune," he told the Doctor, "I yawn because I am bored."
