 CONT: The footbridge of the elephants wagon changes look from scene  to scene. When the elephants enter during the train loading, the  bridge has wooden pads to back it. The pads disappear while the  bridge is used to free Matriarch. The footbridge has a sudden change  of color after Matriarch took the big toss. There is another change  of color after the upper part of the wagon falls down on Matriarchs  head to finish the incident.
