I finally broke down and bought some more D batteries for the busy ball popper yesterday. The kids LOVE this toy, but I have a hard time spending more on batteries than the toy itself probably cost. I waited a little while this time after the batteries died, to make it’s reemergence into the toy rotation that much more special. It was awesome, they played together NICELY with this toy for about 30 minutes. Lily showed her enthusiasm by saying “Ball, ball, ball!” over and over. She never says it once, it’s always at least three times.
