Pump Works

Not to be confused with Pipe Works.

Mario and Luigi in the Pump Works.

Pump Works is a location inside Bowser's body in Mario & Luigi: Bowser's Inside Story. This area appears to be in Bowser's esophagus. It is is accessible to Mario and Luigi when Bowser drinks water from the Sea Pipe Statue in Plack Beach. Drinking water as Bowser floods the area, which allows Mario and Luigi to swim and certain objects to float. Once he stops drinking, the water will drain from the area. Mario and Luigi travel here to search for Princess Peach, but instead they find Toadsworth. This area also features ten Attack Pieces, that once gathered, allow Mario and Luigi to use the Fire Flower Special Attack. Also, it has an obstacle (a cannon that launches food for a giant Chombone) that is required to obtain the Stingler, an item that, once obtained, opens up other areas of Bowser's body.
