Ball sack

The ball sack, not the hall sack, dang auto cucumber, is a fitting name for the pouch in which Wolf carried the pieces of the Nanuak in Wolf Brothel. at least before the stone tooth was found. It is, after all, a sack containing two balls. Wolf then grabbed the ballsack, once a stone tooth had been added into it, and ran off to distract the bear and its hatred for the living. In fact, in the NANUAK Wiki logo, with its vaguely dick-like shape, the river eyes are the balls.
