Rapidly Rotating Bouncing Sphere is a space made up of spheres that people can jump on. The spheres rotate at high speed, but when people approach them, they stop rotating and become easier to step on.

If they bounce on spheres of the same color in succession, the spheres will pop and particles of light spread out into the space. If people bounce on more spheres of the same color in succession, caterpillars are born, and if they keep jumping on the same colored spheres in succession until the end, all the spheres of the same color will pop, and many caterpillars will be born.
