Carousel of Progress basically works like this... The building is made of two circles, one with the seats, and another with the stage. While the stage is stationary, the seats will move to transition from stage to stage. The transitions, on the other hand, are simple to explain. Each animatronic is simply looping. Y'know how with every transition, there's a song? Well, as your entering one scene, listening to the song, another group is exiting that scene and going to the next. So, when your time with that scene is over, they'll sing, and you go to the next set!
