This "wiggly giggly" ball was very disappointing.  I ordered the first one that seemed to be defective, which of course amazon was quick to replace.  The second one came and was no better than the first one.  It would only make those cute little noises if I shook it like a crazy person, but as soon as I would roll it for my little dog, it went mute.  He lost interest in it pretty fast after that so it went back.  I would have kept it for just a regular ball for him but at almost $12, I thought that was a little pricey for a do nothing ball.
