A colorful squishy toy that looks like an innocent stress reliever may hide something parents cannot see: expandable water beads. About 37,000 Squishy Dumpling and Crazy Squib Ball toys were recalled on October 1 after regulators determined that their water beads could expand beyond federal limits and create a potentially deadly ingestion hazard. The latest water bead toy recall covers products sold nationwide, although no injuries have been reported in connection with these particular toys. For families, the bigger lesson is that a soft exterior does not necessarily mean the material inside is harmless. Here is what parents should know before another squishy toy lands in the playroom.
