According to the packaging, the small toys can “grow up to 600% its original size” when placed in water. But if the small toy is ingested, it can expand inside a child’s body and cause intestinal obstructions, the Consumer Product Safety Commission’s said in a statement. “Surgery is required to remove the toy from the body, if ingested.”

Recalled products include the Hatch & Grow Easter Eggs, Easter Grow Toys, and Hatch Your Own Dino. The Hatch & Grow Easter Eggs come with water-absorbing white bunnies, brown bunnies, or butterflies.

The products were sold nationwide between February and March 2017. Consumers with the product should take it back to any Target location for a full refund.
