The correct answer to this open question is the following.
Unfortunately, you did not include the folk tales or any link to access these tales. Without that information, we do not know what you are talking about. We cannot write a summary because you did not attach the folk tales.
However, in order to offer some help, we can comment on the following.
Folk tales are traditional stories passed from generation to generation. These folk tales are an intrinsic part of the culture and tradition of people in one region. So as obvious as it sounds, every region has its own culture and folk tales.
Most of these tales refer to customs and traditions, or stories about strange creatures in the woods, or heroes that existed in the past who delivered great deeds.
Yes in my culture there are folk tales that had been passed through generations since Mesoamerica times. With the arrival of the Spanish colonists, more tales were added to the folklore of our people.
