Door (Wrecking Crew series)

Doors are transit points for monsters to travel between the foreground and background in VS. Wrecking Crew and Wrecking Crew. They can be opened with hammers but will close on their own after a few seconds. Explosions will open all doors simultaneously. When a monster travels to the background, it becomes a harmless blue silhouette.

In VS. Wrecking Crew, doors appear in every phase, excluding bonus stages. Their color matches the stage's color. In two player games, Mario or Luigi can use doors to send Gotchawrenches and unnamed hatchet monsters to harass each other. In single player mode, the monsters are harmless to the CPU-controlled Luigi.

Doors appear in about a fifth of the phases in Wrecking Crew where they behave almost the same. In this game, all doors are green. If all the Gotchawrenches or Eggplant Men are sent to the background in a phase that has more than one, all will freeze for around eight seconds.

Doors are part of some Wrecking Crew challenges in NES Remix.

Trivia

 * These are the earliest functional doors in a Mario game. The only prior appearance of a door is in Mario Bros. for the Game & Watch where it is part of the background.
