Test the waters with our Safety Duck. No need to worry that baby's bath water is too hot to handle. This adorable rubber ducky has the Munchkin White Hot safety disc at the bottom that tells you when the water is too hot, then lets you know that its safe to put your baby in. And, it's just the right size for little hands to hold and cuddle. Watertight so it won't sink, squirt or mildew.
