In Scandinavian folk tales there are many creatures known as the hidden people. These can be Tomtes, Nisse or Huldufólk depending on the country. The Huldufólk in Iceland are so beloved that people build them little houses. Dealing with the hidden people can be tricky – for their natures are wild. They can be helpful and grant wishes, but always treat them with respect! The person who teases one of the hidden people can end up experiencing a nasty trick like a troll booger in their bed!
