The Flash Liquidizer Ultra Dousing Device, abbreviated and better known as F.L.U.D.D. or FLUDD (pronounced "flood"), is a multipurpose water pack from Super Mario Sunshine invented by Professor Elvin Gadd. It features a water tank, two handles, and four interchangeable nozzles. It is possible that F.L.U.D.D. is Mario's equivalent of the Poltergust 3000 used by Luigi. In Super Mario Sunshine only, F.L.U.D.D. is also shown to have an artificial intelligence and is able to communicate with Mario and any other characters by speaking through the nozzle. F.L.U.D.D.'s name is a play on the word "flood," meaning a large mass of water that often causes chaos in a public area.
Super Mario series
Super Mario Sunshine
In Super Mario Sunshine, F.L.U.D.D. can be used by Mario to spray water at objects or enemies by pressing . By doing this, Mario is able to perform a multitude of tasks, ranging from enhancing his acrobatics to cleaning goop off of various surfaces. F.L.U.D.D. can switch between the Squirt Nozzle and either the Hover, Rocket, or Turbo Nozzle (depending on which one Mario currently has equipped) with . As the player continues to spray water with F.L.U.D.D., the amount of water in its tank will gradually get lower. When its tank is completely empty, the player must enter a body of water and hold the button, or collect a Water Bottle before any water can be sprayed again. Throughout the game, F.L.U.D.D. will also often give the player advice on how best to complete a certain task or challenge via a HUD message, which varies depending on the situation.
Mario first encounters F.L.U.D.D. on the ground of the Delfino Airstrip. When he walks over to F.L.U.D.D., it introduces itself to Mario before he puts it on; the player is then shown a tutorial video detailing how to use it. From this point on, Mario carries F.L.U.D.D. around on his back and has access to it throughout the rest of the game. However, there are certain situations in the game when F.L.U.D.D. will be unavailable to the player. For example, it is taken by Shadow Mario every time Mario enters a secret level that has not been cleared at least once. It is also taken by Shadow Mario in Episode 3 of Pianta Village, though in this case the mission involves finding a way around the burning goop that covers the entire village and retrieving F.L.U.D.D.
After Mario defeats both Bowser and Bowser Jr. in Corona Mountain at the end of the game, Mario and Princess Peach fall through the air and land on a small island on the west side of Delfino Plaza. When Mario locates F.L.U.D.D., laying on the ground a few feet from him, it is shown to be damaged and malfunctioning (presumably as a result of Mario ground pounding various weak-points on Bowser and Bowser Jr.'s hot tub, as when it reached three weak points destroyed it began to stutter), asking Mario if "[it] was of assistance" before it shuts down completely. Shortly after, at Sirena Beach, several of the Toads accompanying Mario and Peach to the island present to them F.L.U.D.D., who has been fixed.
Super Mario Galaxy / Super Mario Galaxy 2
F.L.U.D.D. also appears in the Super Mario Sunshine arc of Super Mario-Kun. As with F.L.U.D.D. in the games, it assists Mario, although it expresses more emotion and is more difficult to be with. It sprays Mario's face, causing Mario to yell at it, for example.
Mario Power Tennis
Several F.L.U.D.D.-like water pumps appear in Mario Power Tennis; these heads are used to clear away the goop that can accumulate in the Delfino Plaza Court. Also, in the minigame Tic-Tac-Glow, the player must use balls of water shot by several F.L.U.D.D. pumps to clear away goop in a tic-tac-toe like the game.
F.L.U.D.D. makes a small appearance in WarioWare: Smooth Moves in a microgame, in which it must be used to put out a building fire. The microgame later reappears in WarioWare Gold, where the F.L.U.D.D. is instead used to clean graffiti off the side of the building.

Super Smash Bros. series
F.L.U.D.D. appears as Mario's new down special move in Super Smash Bros. Brawl, Super Smash Bros. for Nintendo 3DS / Wii U and Super Smash Bros. Ultimate, replacing the Mario Tornado from the previous games. When Mario uses the move, he will put F.L.U.D.D. on his back and douse his enemies with water. The attack does not damage opponents, but instead pushes them. F.L.U.D.D. charges when the move is activated and shoots water when the button is pressed again, a longer charge resulting in a more powerful stream of water. F.L.U.D.D. stops charging when it is fully charged, allowing Mario to use it at a later time. Mario can also shield or roll to stop the charging. Mario can destroy projectiles with F.L.U.D.D., and the stream of water can be angled. F.L.U.D.D also appears as a trophy in Super Smash Bros. Brawl and Super Smash Bros. for Wii U.
In Super Smash Bros. for Nintendo 3DS / Wii U, the F.L.U.D.D. move has two custom variations. The first is Scalding F.L.U.D.D., which sprays a short-range stream of water that deals fire damage to opponents. The second is High-Pressure F.L.U.D.D., which sprays a more powerful stream of water and has greater range but also pushes Mario back.
When spraying water, F.L.U.D.D.'s nozzle is next to Mario's head on the right-hand side, while Mario holding a handle with his left hand and holding the nozzle with a right hand. However, in Super Mario Sunshine, F.L.U.D.D.'s nozzle is above Mario's head, with Mario gripping both handles with both hands.
F.L.U.D.D. also appears as a support spirit in Super Smash Bros. Ultimate. When equipped, it grants immunity to sticky floors.
In Minecraft: Wii U Edition, Minecraft: Nintendo Switch Edition and Minecraft: New Nintendo 3DS Edition, F.L.U.D.D. can be found in the miscellaneous section. The empty bucket has been replaced by F.L.U.D.D. with dark blue water, the water bucket is F.L.U.D.D. with light blue water, the lava bucket is F.L.U.D.D with lava and the milk bucket has F.L.U.D.D. with milk. The water bucket F.L.U.D.D. can be used to place water, the lava bucket F.L.U.D.D. can be used to place lava, and the empty bucket F.L.U.D.D. can be used to pick up running water and lava. The milk bucket F.L.U.D.D. can be used to clear the player's status effects and is obtainable by milking a cow. Mario with F.L.U.D.D. on his back is a playable skin.
In Super Mario Sunshine, F.L.U.D.D. is able to use a total of four different nozzles, only two of which can be equipped at one time. Upon starting the game, the Squirt Nozzle and the Hover Nozzle are equipped by default. The remaining two nozzles (the Rocket Nozzle and the Turbo Nozzle) can be equipped by breaking open various Nozzle Boxes located in Delfino Plaza and its surrounding areas (although not all nozzles can be found in certain levels). When equipping either of the remaining nozzles, the Hover Nozzle is replaced by the new nozzle, as one of the equipped nozzles must always be the Squirt Nozzle; the next nozzle that is equipped replaces the previous nozzle. To change between nozzles equipped, the player must press the button. Every nozzle is controlled with .
