The Julekalender is a Christmas story about three "nisser" who have to go from the North Pole and back to the cave in the Norwegian province of Trøndelag to find the life melody of the head nisse who is about to die. However they have to watch out for the evil "Nåså", who during the series comes to live with a potato farmer nearby. The series is based on funny lines containing dialect or a mix between Norwegian and English. The lines are repeated in episode after episode, and if a good line occurs, one of the nisses will say "Hey, that's a good vending (phrase). Maybe we can use that in another episode!" The show is a copy from the danish "The Julekalender" (1991).
