'The Key to Happiness' tells the story of a greedy dragon who has scales made from rubies and gold. In an attempt to possess a scale for themselves, people from a nearby village try to buy a scale from the dragon in return for other material goods. However, the dragon takes the goods for himself and leaves the people poor and desolate. A lowly goat herder who stumbles across the dragon's cave by accident in a storm decides to teach him a lesson. He introduces the dragon to the 'key of happiness'- a magical old key that, when held, can conjure up a feeling of content that the dragon is missing from his lonely life. As the two embark on their journey, the dragon learns that true happiness comes from helping and giving to others, t from taking and receiving gifts.
