The Hustlers

In English folklore, house spirits who like to rattle and knock. They turn into animals and run around the house in the guise of squirrels or cats. They bang on walls, knock on stairs, slam doors, throw bricks and stones at passing people, mess around, jump and shout at night, pull off bed coverings from sleepy ones, extinguish candles from servants, overturn the milk trough at the cowshed and, pouring milk, laugh with evil laughter and much more.

The poltergeist phenomenon is traditionally associated with these creatures. These creatures are descendants of kobolds who have settled all over the world.
