when green flag is pressed every few seconds a clone will appear and go around the screen. press space to clone 1 clone from all the clones on the screen and press the down key to forever change color effect. press up arrow to delete all but 1 clone from each sprite. I definitely advise not to let the clones get to large especially if your device is not very good.
I thought "lets do some clone stuff* and this is what came to mind. please tell me if you want me to add more characters. [no people]
