Coblyn
A coblyn (plural coblynau) is a mythical gnome-like creature that is said to haunt the mines and quarries of Wales and areas of Welsh settlements in America. == Description == In British Goblins, Wirt Sikes describes coblynau as friendly fairies, half a yard tall, very ugly, and often dressed in miner's clothing, carrying tools with which they enthusiastically but ineffectually imitate the work of the miners.
