Happy the Hippo is a 1.25" hard enamel hippopotamus pin with black nickel plating, a rubber clutch, and our logo stamped on the back. Also Included on the backing card is Happy's story and collector number (#62) Happy turned his love for swimming into a full-time career as a swim instructor teaching his fellow Saharan neighbors the joys of being one with the water. Since Paw-pins was created to help animals, for each pin sold, we will donate $1.00 to a charity that helps animals in need. A new Paw-pin is released each month, so please check back to see what new animals you can add to your collection!
