An infant toy sold at WalMart stores is being recalled because it poses a potential choking hazard.

More than 54,000 Reef Rockers are being recalled. The seam on the plastic balls can separate, releasing the small toy inside and posing a choking hazard to young children.

The toy includes a water-filled dome and has four toy balls with sea creatures inside. Lights and music are activated when the toy is shaken.

The Reef Rockers were sold at WalMart from May 2004 through this past January for $8 to $10.

If you have the Reef Rocker, return it to your nearest WalMart store for a refund.
