Query: Like a rock, HARD plastic-needs to be rubber

Unlike other reviewers, I love hearing my dog play with something over and over again, especially if it talks. The "babbling" is very cute, but the flaw with this ball is that it is hard plastic (like a cat toy) and not something many dogs would enjoy because it doesn't bounce and is like a hard rock. Now I don't know about your dogs, but none of my dogs like playing with rocks, therefore this toy is very unappealing to them (not to mention me) because I can't throw it and play with them and have it bounce. Truthfully, this "ball" is really stupid because it's not rubber and will not bounce and since it's so hard, I can't throw it at the risk of hitting one of the other dogs with a rock like object.
