joke was planned. It was to have taken place  when Roger and Baby Herman reached the top of the roller coasters  ridiculously high first lift hill. At the top would have been a  crossroads with a traffic light that turned red, pausing the pairs  car. At this point, the "Long Car" was have zoomed through the  intersection in front of them. Riding in this roller coaster train  was supposed to have been every single animated character that has  ever appeared in a Disney film. Mickey and Minnie were to have been  seated in the front car, while Monstro the Whale from  _Pinocchio (1940)_ (qv) would have been towering over everyone from  his seat at the very back of the train. Disney animators worked for  weeks to get this brief flash of a scene just right. Ancient model  sheets pulled from the studios animation research library, to make  sure every single character looked perfect. Where each character  should go on the train was endlessly debated. However, despite all  the effort put into the gag, it had to eventually be cut. If the  "Long Car" zoomed through the scene as fast as it was originally  supposed to, none of the audience would have been able to recognize  any of the characters. But if it was slowed down, it threw off the  frantic pace of the rest of the short. So the joke was left on the  cutting room floor.
