In Hopi mythology Nataska (also Nata´aska and variants) is the uncle of the family of "ogre Katsinas" who guard Soyok Wuhti (Monster Woman), and who enforce good behavior among the children.
They serve a cultural role of explaining the Hopi way of life, particularly for indoctrinating children in the society's history, behavioral expectations, moral codes, and ritual practices.
[4] In both the mask and figure form, Nataska has a large, long snout, and carries a saw or knife in one hand, and a hunting bow in the other.
[6] The ogres appear again at the Powamuya (bean dance) accompanying Soyok Wuhti to threaten children against misbehaving.
In some versions of the ceremony, they are vanquished or appeased by the end of the dance so as to spare the children's lives, and return to their caves until next season.
