They are a bit smaller because they shrink and shrivel and some even loose their wings. They like to play tricks on humans (like turning their gloves inside out) and they take items which humans still need (like socks). They move into to abandoned Fairy houses.
They collect screws and nails and their favourite foods are onions and salt. Therefore a good way to keep Goblins away is by sprinkling sugar near your Fairy door.
Despite being very devious, Goblins are harmless and if you don’t mind finding your objects moved around the house and small footprints in your curry powder, you can grow quite fond of them.
