(CNN) - Parents, you better double check what's sitting under the Christmas tree.
There's a recall on the toy called Water Balz and its other varieties: Growing Skulls, H-2-O Orbs and Fabulous Flowers. The toys absorb water and can expand 400 times their original size. That's big trouble if a kid swallows one.
This voluntary recall happened after a baby needed surgery to remove it after ingesting last year.
