You Need To Get A Certain Amount Of Shine Sprites. 30-36.
once you go back to delfin plaza with that amount. shadow Mario should appear with it. beat him and you get it in delfino plaza.
Use the turbo nozzle.
hover nozzel
You can run on water if you use the turbo nozzle.
It depends on how many shines you get. when you have enough shines shadow Mario will appear holding a rocket nozzle, turbo nozzle, or a Yoshi egg
It can technically last forever as long as Mario continously refills Fludd with water.
You Get it in Mission 1 and 2 of Ricco Harbor in the first boat you see. there should be a black box. The Turbo nozzle is there and is unlocked forever
I believe you need either 35 or 45. one of the two.
In super Mario sunshine it lets you clean up mud and slime. It also has 3 different interchangeable nozzles. There's the hover nozzle, (lets Mario hover for a short time) the turbo nozzle, (Mario can use this to break open certain doors and get to places quickly with the disadvantage of not being able to turn very quickly) and the rocket nozzle (shoots Mario into the sky to reach new heights). In Super Smash Brothers Brawl it is a non-damaging move that pushes your enemy away from you. Mario's "water squirter" is named Flud.
For most episodes, you just have to unlock it in another episode. To unlock it in Delfino Plaza, you must first obtain 30 Shine Sprites, get the Yoshi, (Also obtained by getting 30 Shine Sprites) and the Turbo Nozzle (Also obtained by getting 30 Shine Sprites) from Shadow Mario in Delfino Plaza. Shadow Mario will then carry the rocket nozzle around.
To get the turbo nozzle in you need approximately 25 shine sprites. You will then chase shadow Mario across Delfino Plaza. After you have squirted him with enough water, he will drop the turbo nozzles and leave. To get the rocket nozzle you need approximately 30 shine sprites. Use the same method as before, and you will have all three nozzles at your disposal while in Delfino Plaza. (Note: these instructions only work in Delfino Plaza. There are some worlds you can enter and get these nozzles)
The rest are scattered throughout the game. Some of them can be bought with blue coins, and others can be found by breaking down doors by using the Turbo Nozzle. The rest are probably in the levels themselves.
