Story of Vikram and Betal:Why did the child laugh?

This time too, King Vikramaditya takes down the Betal hanging from the tree and carries it on his shoulder and moves ahead. Like every time, Betal again tells a story to King Vikramaditya. Betal says…Once upon a time, a king named Chandravalok ruled in Chitrakoot city. He was very fond of hunting. Once he went out to hunt in the forest, while roaming there he lost his way. Tired, he started resting under a tree. While resting he saw a beautiful girl. Her beauty settled in the eyes of the king.
