Roto Disc (Super Mario Land)

Roto Discs are Fire-Bar-like obstacles that appear in Super Mario Land. They appear in the second and third stages of the Chai Kingdom. The orb of flame orbits a Hard Block or Mystery Block, and touching the flame is hazardous. They are completely invulnerable.

Roto Discs are similar to their namesake from Super Mario Bros. 3, and share the same attack pattern.
