Water Shooters are two types of devices that appear in Super Mario Galaxy, first appearing in Honeyhive Galaxy. The first type shoots water similarly to the Squirt Nozzle used by F.L.U.D.D. in Super Mario Sunshine, the only difference between the two nozzles being that Water Shooters are blue in color while F.L.U.D.D. is yellow.
The second type of Water Shooter looks the same as the first, however, instead of shooting water, they produce bubbles. Mario can get into the bubble and float in the air for a time, using them mainly to reach some inaccessible points.
The 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 were in the first section with the fast-moving floor. They also shot bubbles faster than before, though they could be slowed down with a Ground Pound Switch. They also appear in Starshine Beach Galaxy.
