"fear paints the bloody hobgoblin"
In folklore, a hobgoblin is a friendly but troublesome creature of the Seelie Court. The best known is Puck in Shakespeare’s A midsummer Night’s Dream.
Hobgoblins are generally described as small, hairy men, often found doing odd jobs around the house while the human family sleeps, in return for food. Despite being useful, they are fond of practical jokes, and are also easily annoyed. They can be mischievous, frightening, and even dangerous, and are difficult to get rid of.
