Pump Works

Pump Works is a location inside Bowser's body in Mario & Luigi: Bowser's Inside Story that seems to be in Bowser's throat. This area is accessed to Mario and Luigi when Bowser drinks water from the Marine Pipe's Statue in Plack Beach. Once Bowser drinks the water, this area will flood. Once he stops drinking, it will sink. Mario and Luigi travel here to search for Peach, but they find Toadsworth. This area also features Attack Pieces, that once gathered all the ten pieces, Mario and Luigi will learn to use the Fire Flower.
