Initial development had the hot wheels capsule car behind the captive ball sort of like bumblebee in transformers. The car just didn't hold up well with bashing. Then it was considered to be like bart simpson and sit above the plastic and move when the captive ball was hit but this got cut for whatever reason, too.
