F.L.U.D.D.

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. Its name may also be derived from that of Robert Fludd, an inventor who designed many water pumps.
