Roto-Disc



Roto-Discs are fireball-like entities first appearing in Super Mario Bros. 3. Roto-Discs are only found circling gray orbs, which either Mario or Luigi can stand on; Roto-Discs are nearly indestructible, and can only be destroyed by having Mario or Luigi transform into a statue by using a Tanooki Suit and landing on top of a Roto-Disc's gray orb. Aside from Super Mario Bros. 3 and its subsequent remakes, the only other appearance of Roto-Discs was in the Mini-Mario course in Bowser's Castle in Mario & Luigi: Superstar Saga as obstacles that are capable of defeating Mario in one hit.
