Just press the green flag and watch/listen to the music/animation. Yes it takes a while for the animation to start. Be patient. If you don't have headphones it will probably be more boring, because there is a song going.
This is part 4. I've added seconds on to match it with the music, so that you won't have to do anything to it to make it start at the right time. If you leave the 'wait' blocks as they are, it should come up at the right time on the map, once you put it all together.
