David is in his garden picking vegetables when he receives a telepathic message. The message is coming from the king of Siberia. David tells Lisa that they will be gone for a long time, and he builds a sort of bench for them to sit on during the journey. Swift carries them to Siberia, holding the top part of the bench in his mouth. On the first night, they have to take shelter from a storm. In the morning, the storm is over, and the king's messenger comes to greet them. On the way to the palace, David tries his hand at skiing, and impresses the other gnomes. At the palace, the king tells David that there is a bear stuck in a high tree, who has been there for several days. David gets help from some other gnomes to save the bear.
