I need information on the Comanche monster, Pia Mupitsi the Cannibal Owl?

"The Comanche looked upon their children as their most precious gift. Children were rarely punished. Sometimes, though, an older sister or other relative was called upon to discipline a child, or the parents arranged for a boogey man to scare the child. Occasionally, old people donned sheets and frightened disobedient boys and girls. Children were also told about Big Cannibal Owl (Pia Mupitsi, derived from Mupitz, see Comanche language) who, they were told, lived in a cave on the south side of the Wichita Mountains and ate bad children at night."

"There were also tales that the oldest shared with her. Stories of the Cannibal owl that came in the night and took bad children, throwing them over its shoulder into it's burden basket onto a long, sharp spike. Some said that the whites were like the Cannibal owl and would eat Numa children if they cried too loud in the night."

The only thing I can give you that is different than what you already have is that Pia means mother and Mupitsi or Mupitz means Owl..... I find only the same that you found..... "The Comanche looked upon their children as their most precious gift. Children were rarely punished.

Sorry

The Comanche Indians saw children as a gift and therefore rarely punished them. An older sibling, another relative, or a “boogey man” administered any discipline of a child. The “boogey man” was another adult, usually an elder tribesman, who wore sheets to frighten rebellious girls and boys. If that did not work, they were told the story of the Pia Mupitsi or the Big Cannibal Owl that lived in a cave in the mountain and ate bad children at night.
