Dung beetles are rather backwards animals. Firstly, the don't eat normal food, but rather eat the food waste of other animals. Secondly, when they come upon a piece of dung they particularly like, they roll the dung into a ball and walk backwards with it, moving the food to a safe place for storage and feasting
. They also can use these dung balls as a place to lay larva.
My build uses 99 pieces.
