Watch our movie of nothing! Using background music! Click the green flag to start outside. When you see a response that you are about to go inside or see a movie, click Yes or No at the bottom. If you hear music in the background, this is where the movie gets played. You can also play the movie again and again if you want to if it's just the way it is.
I even used Scratch 1.4 for the different font of The End. The backdrop name block introduced in Scratch 2.0 tells if you are outside or inside, so I even did it here!
