Editing Shrinking platform

'''Shrinking platforms'''<ref>Black, Fletcher. ''Super Mario Galaxy'' [[Prima Games|Prima]] Official Game Guide. Page 120.</ref><ref>Browne, Catherine. 2010. ''Super Mario Galaxy 2'' Prima Premiere Edition Guide. Page 249.</ref> are [[platform]]s with a green checkerboard-like design found in ''[[Super Mario Galaxy]]'' and ''[[Super Mario Galaxy 2]]''. When [[Mario]] or [[Luigi]] steps on one, it immediately begins to shrink. Eventually, the platform disappears, leaving only the metal frame around it. Shrinking platforms are mostly used in areas where Mario or Luigi must walk carefully to avoid falling but quickly enough to avoid falling through. Some planets are entirely made up of shrinking platforms. The objective of these planets is to collect all of the [[note]]s around the planets themselves before all of the shrinking platforms disappear. Player 2 can help in Co-Star Mode by freezing a platform after Mario or Luigi has stepped on it, though the platform starts to shrink once Player 2 lets go. Shrinking platforms can be found in several [[galaxy|galaxies]], including the [[Hurry-Scurry Galaxy]], the [[Sea Slide Galaxy]], the [[Toy Time Galaxy]], and [[Mario Squared Galaxy]].
