The egg babies collection is one of the greatest dog toy inventions. Each of the egg babies comes with 3 squeaky eggs inside. They are stored in a little pocket inside the fish (they also make ducklings, a platypus, hedgehog and others). It took my bulldog a little while to get the eggs out, but he was totally transfixed by this thing until he did, and then after he loved playing with the squeaky eggs. It's a great activity for active pups, and very entertaining to behold!
