In Wrecking Crew for the NES, on certain levels, if you hit the bombs in a certain order quickly, the Golden Hammer will appear. It lets you move and break faster, as well as having the special property of allowing you to float across floors if you mash the button while moving, exactly like the one in Brawl appears to work.
