The fable about how two animals help each other and have the moral "treat others as you would like to be treated" is one of the famous Aesop's collection of fables "The lion and the mouse". It is also considered a folktale that originally belonged to the oral tradition. Folktales which have been passed from generation to generation (such as fables, myths, legends and urban legends) intend to teach a lesson or a moral by means of animals' personification as well as their actions.
