Mario has returned to the Mushroom Kingdom from a trip, only to find that Bowser has started a construction campaign of building new hideouts. The construction projects are depriving the kingdom's plants of sunlight and thus, Mario decides to demolish the projects with his hammer. Along the way, he meets his old enemies from the original Wrecking Crew, including former rival Foreman Spike.
This Japan-only sequel to the original game takes a more competitive approach, giving two opponents their own sides to demolish as many panels as they can. Once one of the sides is completely filled up, the other player wins.
In this run, pirohiko takes advantage of a shortcut that humorously ends a level instantly if three lines of at least three panels of the same color overlap.
