My favorite Hammerhead

I originally bought one of these for my husband, but I loved it so much, I bought myself one as well. I love it. It's soft, cuddly and so adorable. My 3 kids all want one now, too! Thank you, Slumberkins, for another amazing product!

I love it!

I bought this Hammerhead KinFlip for my husband, and he loves it. It's so soft, the planet it turns into is awesome. The quality is unmatched. I love it so much I bought one for myself.
