150 miles due south of london, lives Harold the Halibut.
Harold lives in a small shipwreck along with a wife and two daughters, and are next door neighbours to Colin the Cod, and Sammy the Skate.
They all live directly under one of the busiest shipping lanes in the world, and the area is either known as the English Channel (if you are English), or La Manche (if you are a Froggie).
