Ring Burners are robotic enemies first appearing in Super Mario 3D World. They appear in only three levels: Cakewalk Flip, Rainbow Run, and Champion's Road. When the player ventures near one of these enemies, they blast either square or circular plasma rings outward from their center. They have the same insignia commonly found on Bill Blasters and closely resemble earlier Beamer enemies from the Galaxy games in both appearance and function. As with Sentry Beams, Ring Burners can be disabled as long as the player stands on one. They cannot be destroyed by any means.
