Flash Liquidizer Ultra Dousing Device

F.L.U.D.D. (Flash Liquidizer Ultra Dousing Device), a water-squirting accessory made by Professor E. Gadd, is a new element in Super Mario Sunshine, which Mario uses to complete all his missions. When Mario first acquires F.L.U.D.D., he can spray water and hover in the air using its nozzles. Two other nozzles can be unlocked later in the game to extend F.L.U.D.D.'s functionality; the Rocket Nozzle, which propels Mario high into the air, however, there is a small limited time Mario can be in the air. The Turbo Nozzle lets Mario sprint at high speed on land and water, and break down doors.

F.L.U.D.D.'s nozzles
Throughout the game Super Mario Sunshine Mario will acquire different nozzles that F.L.U.D.D. can use. By pressing the X button Mario can switch through available nozzles.These include:
 * The Spray Nozzle, sprays water at foes or objects by holding the R button lightly. Comes with F.L.U.D.D. at the beginning of the game, by holding down the R button all the way on the controller he can aim the water.
 * The Hover Nozzle, allows Mario to hover over gaps and acts as a higher/longer jump in some situations. Comes with F.L.U.D.D. at the beginning of the game. By pressing R, Mario hovers above the ground for around five seconds.
 * The Rocket Nozzle, blasts Mario into the air. Has to be unlocked to use it, and is operated similar to the other nozzles.
 * The Turbo Nozzle, blasts Mario across long bodies of water and capable of smashing objects. Only appears a few times throughout the game.

Super Smash Bros. Series
F.L.U.D.D. appears in Super Smash Bros. Brawl as Mario's Down-B Special Attack. It only had the spray nozzle, whose water does not do any damage, though it does push other fighters back. It cannot hold as much water as it did in Super Mario Sunshine.

Trivia

 * Boss fights from older Mario games appear in the bottom left corner when F.L.U.D.D. scans Mario.
