There is a song if you want it :) Basically the people just dance, the letters change color (except for the pixellated one), and the drums beat.
I made this by finding figures with multiple costumes. I made their script with a "When *flag icon* pressed" at the top, "wait 0.1 second", and "next costume". There is a "forever" block around the "next costume" and "wait 0.1 seconds" block.
