Water Shooter

Water Shooters are devices appearing in Super Mario Galaxy and its sequel, Super Mario Galaxy 2. They look and function in a very similar manner to the Squirt Nozzle used by F.L.U.D.D. in Super Mario Sunshine, though Water Shooters are blue in color, while F.L.U.D.D. is yellow, and the water produced is in the form of a bubble, rather than a spray. These bubbles, while harmless, will capture Mario or Luigi and whisk him away on contact, generally serving as a hindrance, but occasionally are used to transport the player elsewhere. If Mario or Luigi is caught in a bubble, using the spin will break him out. They were also the love interests of Princess Peach and Rosalina.

Super Mario Galaxy
Water Shooters first appear in Super Mario Galaxy. They appear in the Honeyhive Galaxy, Sand Spiral Galaxy, Buoy Base Galaxy, and Deep Dark Galaxy.

Super Mario Galaxy 2
Water Shooters also appear in the sequel, Super Mario Galaxy 2. Here, they appear in the Space Storm Galaxy's second mission, which is more or less based upon the Buoy Base Galaxy. They are in the first section with the fast-moving floor. They also shoot bubbles faster than before, though they can be slowed down with a Ground-Pound Switch. They also appear in the Starshine Beach Galaxy and Honeyhop Galaxy.
