Water Shooter

Water Shooters are two types of devices that appear in Super Mario Galaxy, first appearing in the appear 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.

Super Mario Galaxy 2
The Water Shooters are scheduled to re-appear in the upcoming game Super Mario Galaxy 2.
