Háno go hunting rabbits in winter towards Sun shrine. They kill many, and return still hunting. Másauwuu hunts during night and sleeps all day, Háno follows cotton-tail, which jumps down just where Másauwuu is sleeping. They follow, making great noise. Másauwuu jumps up quickly and runs. Runs against rock several times and perforates his head and blood streams down. He used to have white head, but now has bloody head. He has much game, which Háno distribute, and proceed home.
