Spring Vault

Jump Beamers are purple, spring-like robots that appear in Super Mario Galaxy and its sequel, Super Mario Galaxy 2. They act as both enemies and helpful objects, attacking by sending out a circular laser in the area around them, but they can be jumped on and used as a spring, allowing Mario or Luigi to reach areas he otherwise would not be able to reach, similar to the Jump Guarder and Spring Topmen.

Super Mario Galaxy
Jump Beamers first appear in Super Mario Galaxy, making their debut in the Flipswitch Galaxy, where one guards the Power Star. They also appear in the Battlerock Galaxy and the Dreadnought Galaxy. Jump Beamers are stationary enemies that fire lasers in a circular shockwave formation, which will damage Mario or Luigi if he makes contact with them. They cannot be destroyed by any means, but they are able to be stunned by either jumping on top of them or firing a Star Bit at them. If Mario or Luigi jumps on top of a Jump Beamer twice, the spring beneath its head becomes exposed and it can be used as a Springboard.

Super Mario Galaxy 2
Jump Beamers reappear in Super Mario Galaxy 2, behaving identically to their first appearance. Only one appears in the game, being present in the Space Storm Galaxy.
