Fun:King Log and King Stork
Once upon a time there was a group of frogs who lived in a small pond happily under the benevolent rule of their leader King Log. Admittedly, there were some things that were a bit humdrum, but by and large they were happy. One day a Stork appeared and told them that if he were allowed to rule, then all sorts of interesting things could happen. He could fly up with them to show them the big wide world and even, with his strong beak and claws make their pond better by adding to it and removing rubbish. So the frogs allowed the stork to become joint ruler with King Log. Unhappily King (as he now was) Stork, in addition to doing all sorts of interesting things for the frogs, also liked to eat frogs. After a while there were no frogs left.
No moral.
