Arkan Sonney are fairy pigs from the Island of Man that are supposed to bring good luck if one is to capture it. For this reason, they're also called "lucky piggies".
Some say Arkan Sonney are similar to hedgehogs, but other pretend they look like pigs with long hairs.
Arkan Sonney flee any humans, but they are said to bring good luck to one who catches them.
In Manx folklore, if you catch a lucky piggy, you will always find a silver piece in your pocket.
