Click (not drag) a sprite for other sprites to do a dance, and whenever the sprites hear a loud sound, they change color. When they hear a low sound they do something else. Note: if you have a very responsive mouse, trackpad, or pen, the dance may not always work properly. Also, if you click 'Deny' for Microphone access, the color changing will not work.
Sprites made in vector mode. Reference and colors from Bulbapedia.
