The Grandmother Katsina (Hahay-i wu-uti) or Happy Mother shares with Crow Mother the title of Mother of all the Katsinam. Her husband is said to be Eototo and her children are the monsters, the Nataskas.

She appears during the Bean Dance (Powamuya), the Serpent Ceremony and at Niman. She speaks in a high voice and is very talkative. Flat carvings of the Grandmother Katsina are given to Hopi infants. As a young girl matures, she receives larger, more detailed forms of the Grandmother Katsina.
