Burner

Rocket Engines are hazards found on the Airships in Super Mario Bros. 3.

A first glance, a Rocket Engine looks just like a Bill Blaster, but the engines shoot flames instead of Bullet Bills. The flames stay blowing for a few seconds, then stop for a while. Mario and Luigi must use this time to navigate through or around them. In addition, Rocket Engines can be mounted on either wall, the flor, or the ceiling, so their flames can blow in any direction.

Tanooki Mario, in statue form, can temporarily disable the flames, but only until the next time.
