Ball Beamer

Ball Beamers are mechanical enemies with nuts on top of them that appear in Super Mario Galaxy. One also has a screw through the nut. Ball Beamers appear on opposite sides of spherical planets. Ball Beamers appear in the Buoy Base Galaxy and the Deep Dark Galaxy. They are immobile enemies that emit circular shockwaves that travel around the circumference of the planet, damaging Mario or Luigi if he touches them. The bolted Ball Beamers can be unscrewed by Mario or Luigi, which opens up the inside of the planet they are stationed on, while the other ones are unable to be damaged by normal means. Bolts from them also appear in the Toy Time Galaxy. Unlike Ball Beamers, these bolts do not shoot a laser beam.
