Burners, also known as Rocket Engines or Flamethrowers, are blazing hazards found throughout the Newer Super Mario Bros. series.
In Newer Super Mario Bros. Wii, Burners appear as grey cylinders with slight indents near their top and their bottom. On one side of the Burner, an orange fire blows out. A variant of the Burner, the rotating Burner, looks like a Cannon except it's grey instead of black.
In Newer Super Mario Bros. DS, Burners appear as golden cylinders with slight, brown, indents near their top and their bottom. Like in the last game, Burners emit an orange fire out one of their sides.
Burners will stay in place and can emit a 3 to 5 block-long row of fire at certain intervals. By this, the flames stay blowing for a few seconds, then stop for a while. The player must use this off-time to navigate through or around them. In addition to this, Burners can be mounted on either walls, floors or ceilings, so their flames can blow in any direction.
In Newer Super Mario Bros. Wii, a special type of Burner can be found. They're called rotating Burners, and they act the exact same as a normal Burner except for the fact that they can turn their flames 180° degrees and their fires never go out.
