Remember at Christmas (2009) well Zhu Zhu pets were the hottest thing on the market at Christmas. Well it seams that quite a few are dying and the little wheels are no longer moving.
Ok so if your child is left looking sad with a broken Zhu Zhu pet then there is a possible fix for it.
If that doesn't work they if you have your receipt then you can take it back to the store in most cases. If you can't find your receipt then you can contact the manufacture zhuzhupets.com
