Originally a special in-joke was planned. It was to have taken place when Roger and Baby Herman reached the top of the roller coaster's ridiculously high first lift hill. At the top would have been a crossroads with a traffic light that turned red, pausing the pair's 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) 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 studio's 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.
