Roto-Discs are found orbiting gray or red orbs, on which it is possible for [[Mario]] or [[Luigi]] to stand. Sometimes, they instead circle [[? Block]]s or simply circle with nothing in the middle. Roto-Discs are nearly invulnerable; they can be destroyed if [[Statue Mario]] lands on top of one. '''Duo-Roto-Discs'''<ref>{{cite|title=''Nintendo Power'' Volume 13|page=59|date=June 1990|language=en-us|publisher=Nintendo of America}}</ref> can also be found, and they consist of two Roto-Discs circling the centerpoint; they may circle in the same direction or in opposite directions. If the player destroys one, the other disappears.
