, an El Segundo, California-based toymaker, said it’s recalling both full-size and mini versions of its robotic baby shark toys that have hard plastic top fins, which pose the injury risks.

Twelve injuries have already been reported with Zuru’s full-sized Robo Alive Junior Baby Shark Sing & Swim Bath Toys — after children sat or fell on the now-recalled products.

Nine of these cases required stitches or medical attention, according to a Thursday release from the .

While injuries have only been reported with these full-sized toys so far, Zuru is also recalling Robo Alive Junior Mini Baby Shark Swimming Bath Toys “out of an abundance of caution.â€

Consumers in possession of the recalled toys are instructed to stop using them immediately and contact Zuru for a full refund.

To get the refund, customers are asked to cut off or bend the tail fin, write “recalled†and a registration code on the body of the baby shark and upload a photo on a site dedicated to the recall.
