Water Shooter

Water Shooters are a type of devices that appear in Super Mario Galaxy. Despite their names, are nozzles that shoot bubbles, which Mario can get one and float in the air in a period of time within the bubble, using them mainly to reach some inaccessible points. They first appear in Honeyhive Galaxy. Fire Shooters are another version of these, that instead shoot fire.

Trivia

 * Water Shooters look like very similar to the Squirt Nozzle used by F.L.U.D.D. (with the difference of that Water Shooters are blue nozzles).
