Editing Screwtop

In ''[[Super Mario Galaxy]]'', bolts most often occur in industrialized [[Galaxy|galaxies]], such as the [[Battlerock Galaxy]] and [[Buoy Base Galaxy]]. Performing a [[spin]] while on top of a bolt embeds it into the ground and triggers a nearby event, such as the shifting of a platform. Bolts are very similar to [[valve]]s, green objects that usually release [[Star Bit]]s when spun. There are two varieties of bolts: a '''blue screw'''<ref>{{cite|author=Black, Fletcher|title=''Super Mario Galaxy: PRIMA Official Game Guide''|format=Collector's Edition|location=Roseville|publisher=[[Prima Games]]|date=2007|page=104}}</ref> with a Phillips head, and a '''gold screw'''<ref name=pg238>{{cite|author=Black|page=238}}</ref><ref>{{cite|author=Black|page=258}}</ref> (also called a '''golden bolt''',<ref>{{cite|author=Black|page=160}}</ref> '''yellow screw''',<ref>{{cite|author=Black|page=236}}</ref> and '''golden screw'''<ref name=pg238/>) with a slotted head. Both bolts often appear together in the same galaxies. During [[Heavy Metal Mecha-Bowser]], blue and gold screws are embedded into the body of [[Toy Time Galaxy#Mecha-Bowser|Mecha-Bowser]]. Unscrewing them causes its body to fall apart. In the Buoy Base Galaxy, a gold screw is attached to a [[Ball Beamer]] and disengages it when spun. A bolt can only be used once, flattening it with the surrounding ground.
