Are small spiny skinned animals that attach themselves to the caverns of the ball sack and eat away any Duck Butter residue. The spines are used to move around the ball sack and penis area, also for trapping drifting Duck Butter for food.
(Shower Scene) Hey Bob, it looks like you have a case of Ball Urchins. Use some of my Ball Urchins cream, it will get rid of those creatures fast!
