Water Shooter

A Water Shooter is an obstacle that appears in Super Mario Galaxy and Super Mario Galaxy 2. Despite their name, they don't shoot a spray of water, and instead spray bubbles.

Super Mario Galaxy
They first appear in this game. The bubbles can trap Mario or Luigi. They can be either helps, or hindrances. They can either transport Mario or Luigi to unreachable places, or leading them to a trap. Using a spin move can free the player from these bubbles.

Super Mario Galaxy 2
They appear in Space Storm Galaxy's second mission, remaining unchanged from their first appearance. They can be slowed down with a Ground-Pound Switch. They also appear in Starshine Beach Galaxy and Honeyhop Galaxy.
