F.L.U.D.D.

F.L.U.D.D. is Mario's Down B in Super Smash Bros. Brawl, taken from Super Mario Sunshine. After taking it out, holding down and B will charge it up, which can be done anytime (even when shielding). Letting go of down and B fires a stream of water that does no damage, but does have knockback, potentially making it an excellent Edgeguarding move.

• F.L.U.D.D. stands for Flash Liquidizer Ultra Dousing Device.
