Kwajo's father makes traditional small figures. One day, he makes him a little brass drummer who comes alive and transforms Kwajo into a land of proverbs and riddles. It is a land where the figures represent money, and the people are citizens in a powerful kingdom. Kwajo is tempted by riches but must first decode a series of riddles and symbols. He falls at the last test, but nonetheless learns an important lesson.
