3.75" Light-Up Dancing Ball

We bought this for our dog and he goes absolutely nuts chasing it around the kitchen floor. The sound effects are loud and clear, and the vibration makes it really unpredictable. It's been a solid hour of entertainment for all of us.

The vibration is surprisingly strong for such a small ball—my toddler couldn't stop laughing as it danced across the floor. Having the batteries included right out of the box was a nice bonus.

My kid loves pressing the button to get this ball dancing and singing, and the built-in sound effects are a fun touch. It does eat through batteries pretty fast with all that shaking, but the included ones got us started right away.
