Well, I've hooked up with some interesting things, but I've never had one of these on my ball before!
Very cool rental toy! And while I was returning it, I drove past some kids selling lemonade at a stop sign. "Always buy anything a little kid is selling at a stand," my mother used to say. Before I could order a cup of lemonade, they all started shouting "Cool! A transformer! Make it change! What does it turn into???" It was the funniest thing!
