Fire Shooter

Fire Cannons are a type of devices that appeared in Super Mario Galaxy and its sequel, Super Mario Galaxy 2. They are similar to Water Shooters, but as their name suggests, they shoot fire instead of water. They resemble the nozzle part of F.L.U.D.D. from Super Mario Sunshine, except in red.

Super Mario Galaxy
In Super Mario Galaxy, their nozzles shoot long-ranged flames at Mario or Luigi. They are first found in Bowser's Star Reactor and re-appear in the Deep Dark Galaxy, Bubble Blast Galaxy, one fireball-shooting one on Mecha Bowser in the Toy Time Galaxy, and two others on the Undergrunt Gunner Planet from the same galaxy aforementioned. These Fire Cannons resemble F.L.U.D.D., however their nozzles are red instead of yellow.

Super Mario Galaxy 2
Fire Cannons return in Super Mario Galaxy 2. They only appear in Bowser's Galaxy Generator, where they shoot fireballs at Mario. The ones that shoot flames do not reappear in the game.
