Go to the scene where Littlefoot and Chomper are being chased by the two Sharpteeth. They jump onto this log over a big gap in the ground. Then Littlefoot falls into a hole and gets his right back (hind) leg stuck. The Sharpteeth go over to the log and Chomper starts talking and roaring to them. Realizing that Chomper is their son, Chomper climbs on his mother's head, and they walk away. Littlefoot gets his foot unstuck and walks the opposite way on the log. But just before he jumps off it, the camera cuts to a frontal shot of him jumping off of the log, then lo, and behold!!! There's no gap in the ground!! What gives?!
