Those hippo play pads, seem to be in high demand and I tried to order from 3 different places (still waiting for refund from one!). We were able to find one supplier that still had them when we ordered. For those of you interested in the Hippo puppy play pads try this place bowsawowsa.com. My puppies are to little to see if it's a hit yet.
It is stuffed and has toys and squeekers on it, there are area's like the ears and legs that have something in them that makes a krinkling sound like a potatoe chip bag. You can lay it on the floor or hang it on side of cage for puppies to play with or they can snuggle up on it to nap.
