I helped my nephew make this. He remixed the script from evhan55's classic Scratch project, Robot Dance. He likes that the grey and black and white parts in that and this project don't change color. The tricky part was that the character on the top was bouncing in different directions because the trapeze was triggering "if on edge bounce" from the top edge. So we first tried changing the script, then he moved it down a bit so it doesn't touch the top edge, only the sides.
