We got the "B" troop a "willow ball." it looks like a piece of wicker furniture except it's rolled up into a ball. Well, they systematically chewed off lenghts of the sticks and ran around the room with those sticks in their mouths. Then Barbie grabbed a stick away from Buddy and they played "king of the hill" with it on their favorite armchair....
....That was at midnight. This morning when we woke up, no less than 20 pieces of the willow ball were strewn all about the room... But the ball is still a ball and there's probably another week's worth of life left in it.
