Editing Grate

'''Grates'''<ref>{{cite|author=Browne, Catherine|title=''Super Mario Galaxy 2: PRIMA Official Game Guide''|location=Roseville|publisher=Random House Inc|date=May 23, 2010|page=148, 150, 151, 153|isbn=978-0-30746-907-6}}</ref> appear in ''[[Super Mario Galaxy 2]]'' as disc-shaped objects in [[Flipsville Galaxy]] that grant a connection between two different surfaces of a platform. [[Ground Pound|Ground-pound]]ing on a grate causes [[Mario]] or [[Luigi]] to flip to the other side of the platform, changing gravitation and allowing him to walk on that side. Simply falling off the platform does not switch the force of gravitation. Grates are also helpful in defeating certain enemies. Pounding a grate while a [[Pupdozer]] walks over it is the only way to defeat the enemy. Grates are featured during the mission [[Flip-Flopping in Flipsville]]. Moreover, grates play a major role in the battle with [[Glamdozer]], where the player needs to use them and slam her from underneath four times in order to defeat her. However, during battle, Glamdozer often shoots large blobs of [[lava]] that can fill in the grates temporarily, rendering them unusable during that period of time. However, Mario or Luigi is unable to use grates if [[Chain Chomp|Chomp]]s are on the other side.
