Roughly 7.5 million Baby Shark bath toys have been recalled due to a risk of impalement. The water toys are sold at Walmart, CVS, Dollar General, Family Dollar, HEB, Meijer, Target, TJX Companies, Ross, and Walgreens. They're also sold online through Amazon and other sites.

This recall includes both versions of the toys: the full-size Robo Alive Junior Baby Shark Sing & Swim Bath Toys and the Robo Alive Junior Mini Baby Shark Swimming Bath Toys. The newest toys, which have a silicone fin, are not part of the recall.

"We want to assure our customers that we are committed to the highest levels of safety and quality of all our products, and we have implemented measures to prevent future incidents by working to promptly remove these products from retail and replace them with a newly designed product," Zuru, the company behind the Baby Shark bath toys, wrote in a statement.

The toys have a hard plastic top fin that could impale, cut, or puncture a child's skin if they fall or sit on one of them. There have been at least 12 reports of children being injured by the bath toys, including nine children who required stitches or medical attention.

If you've bought one of the recalled Baby Shark toys, you should immediately stop using the toys and contact Zuru for a refund.

Here are instructions for consumers:

• Disable the tail fin (by cutting it on the full-size bath toy or by bending it on the mini-size bath toy)
• Mark the body of the shark bath toy with the word "recalled" and the unique code provided during registration for the recall
• Upload a photo of the product, showing it's disabled and marked, to recallrtr.com/bathshark
• Upon receipt of the photo, Zuru will issue a refund to purchasers in the form of a prepaid virtual Mastercard
