An Arkan Sonney (literally lucky urchin or plentiful pig), is the Manx word for hedgehog. In Manx folklore, is a type of fairy creature which looks like a pig with long prickly hairs. They are said to bring good luck to one who catches them. For this reason, they're also called "lucky piggies". They flee from humans, and are very quick, making them difficult to catch. If however you do manage to catch an Arkan Sonney it is said that you will find a silver piece in your pocket.
