In "Little Polar Bear: A Visitor from the South Pole", Lars embarks again on exciting adventures. First, he and Robby discover a ship lost at sea, then he drives away evil bandits and finally a strange bird appears at the North Pole: Caruso, the singing penguin. He is so funny that even the continuously sad lemmings can laugh again. Only the three bullies - polar bears Kalle, Nalle and Palle - dislike the "Foreigner" and abduct him. But Lars rescues Caruso with the help of his friends and finally the lemmings are happy again.
