Huldra was sais to be a seductive forest spirit from Scandinavian folklore. The name comes from an old Norse word meaning hidden or covered. It was said that the Huldra tricked men into marrying them to enable them to eliminate the "hole in their back"! They were also rumoured to steal or swap their children!
But theres no need for anything like that in the lovely locality of Spring Farm!
