@u29jdt the ball is printed inside and no breaking is required to free the ball, mine arrived rolling around :) @Aimhigh i wouldn't give the 2 year old this item... in fact, I wouldn't trust a 2 year old with anything...

Was the ball printed as an attached piece that required thin pieces to be broken to free the ball?

Is this strong enough to survive a 2 year old playing with it?
