The story aptly demonstrates that it is better to have no one ruling over you than have a cruel ruler. The frogs requested Jupiter for a King to rule over them, but were unhappy when they realized that the ruler sent to them was mild and unimposing. Upon requesting for another King, the frogs' happy and carefree life turned into a nightmare. Who did Jupiter send and what did the new King do?
