Have no fear...There is a substitute!!! The ToyShoppe Playables recently came out with Durables. And, I am happy to report that they are a plus with my crew. I would highly suggest the green ball. It squeaks just like the old soccer ball did but is much improved in the area of durability. So, not as many trips back to PetSmart for replacements.
