|| Well make up your mind. Is it water or fire?
— Patrick Star, "Pet Sitter Pat"
A flamethrower is a weapon that appears in the episodes "Patty Hype," "Pet Sitter Pat," "Are You Happy Now?," and "Grandmum's the Word." As its name suggests, the flamethrower shoots out a jet of flames.
There are two types of flamethrowers: a tube-like one that Mr. Krabs owns and a high-tech gun that Patrick, Fiasco, and Plankton own.
