Query: Beware - Treads will hurt fingers

I bought this toy for my 9 month old son and he loved it. When we first gave it to him, he chased it and mashed the buttons to make it giggle and go. Within 2 minutes of playing with it, he picked it up and promptly got his finger stuck between the tread (which has plastic teeth vs a rubber band) and what I'll call the wheel well. One thing that is cool about this toy is that it moves very fast on a variety of surfaces, which means that those plastic teeth are moving pretty fast and really hurt. When I placed my finger next to it, it caught me and I could feel where it was ground by the teeth for at least ten minutes; not constant pain, but I could tell where it had got caught when I cared to notice.I was very surpised with this because it is made my Little Tikes. We have a lot of their toys, etc, but I cannot recommend this one.We have talked to Little Tikes and they are sending us another toy as a replacement.
