Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, one night, Moko misses his country filled with sun and heat. Alarick, wanting to comfort him and make him feel welcome, offers to show him a great show in the sky. Moko, who thought he had seen all of the wonders the sky had to offer in his country, sees his first northern lights. Amazed, he thinks that in this country the sky can soothe a saddened heart and that Alarick, child of the cold, has proven to be a warm and welcoming friend.
