Unga-Chuk
Unga-Chuck of the Nsswe Neppe, is a mythological character from the Meskwaki-Sauk tribal folklore. The tale comes from the Fox and Sac tribes in what is now present day central Iowa.
The Sauk (or Sac) tribe and the Meskwaki (or Fox) tribe. The Meskwaki and Sauk Indians were related to each other and spoke the same language, but they were politically independent. However, the Fox tribe was nearly destroyed in a war with the French, and the surviving Fox Indians fled to the Sauk villages for protection. The two tribes merged into a single tribe called the Sac and Fox. Most Sac and Fox people still live together today. The version below was collected by John Tobin in his book With No Intention.
