Somalis also have a rich oral tradition when it comes to ancient folktales, stories which were passed on from generation to generation. Many Somali folk tales of work and life are so old and ubiquitous their authorship is unknown. Tales such as "Dhegdheer the cannibal woman" were told to little children as a way to instill discipline in them since the dreaded "Dhegdheer" was said to pay a visit at night to all those who had been naughty. ""Coldiid" the wise warrior" is another popular Somali folktale with a positive message regarding a "waranle" (warrior) who avoids all forms of violence. For this abstinence, he is looked down upon by his peers. However, in the end, he manages to show that violence is no way to earn either respect or love. "A Lion's tale" is a popular children's book in the Somali diaspora wherein two Somali immigrant children struggle to adapt to life in a new environment. They find themselves surrounded by friends that strike them as greedy, only to magically return to Ancient Somalia where they live out all of the popular Somali folktales for themselves. "A Lion's tale" has also recently been developed into a school play.
