Continuity mistake: Once Spunky is kidnapped and Hunky takes off chasing the truck, you see the truck going along the road passing just some grass and one large rock on its left side. Once Hunky catches up to the truck, it cuts to a side view close up of him and Spunky's head sticking out the back, and suddenly the truck is passing a very large rock that was not there in the previous shot. The rock is taller than the truck, so it would have shown. And then it's very obvious the background is then looped as the same huge rock passes the truck every few seconds repeatedly. (00:01:35)
