Brooklyn

 is a borough of the American state of New York City and the hometown of Mario and Luigi in certain media of the Super Mario franchise.

One of Brooklyn's first mentions in a game is in Mario's Time Machine, in which, upon being asked if he was from Italy (due to his accent) by an imperial ruler in China, Mario says that he is from Brooklyn, New York. Of course, granted the time period, the feudal lord did not know what Brooklyn was.

According to early media such as the instruction booklets for the SNES version of  and console conversions of Mario is Missing!, the Super Mario 64 Shogakukan guidebook and Nintendo Power guides, as well as the DIC cartoon shows, Nintendo Comics System, and The Super Mario Bros. Movie, Mario and Luigi are from Brooklyn.

The Super Mario Bros. Super Show!
In The Super Mario Bros. Super Show!, it is shown that Mario and Luigi ended up in the Mushroom Kingdom by getting sucked down a Warp Pipe connected to the drain of a bathtub that they were unclogging. In the cartoon episodes, Mario and Luigi often make reference to their former lives in Brooklyn, or lament how they wish to return home; the Brooklyn Bridge is seen in several of the episodes. The live-action segments all took place at the Mario Brothers Plumbing shop in Brooklyn, where the Brooklyn Bridge can be seen from the building and is also mentioned on a few occasions.

In the episode "Brooklyn Bound", Mario and Luigi meet up with Salvador Drainotto, a fellow Brooklyn plumber who had been lost in Mushroom Kingdom for thirteen years. However, Salvador Drainotto had discovered a one-way drainpipe to back to Brooklyn, which could only be used once. With Mario and Luigi's help, Salvador Drainotto was able to reach the pipe, and offered Mario and Luigi to come along. Mario and Luigi almost go along with Salvador Drainotto, but decide to stay behind in the end to save Princess Toadstool and Toad from Koopa Khan and the Koopa Pack.

Brooklyn is also featured in the episode "Plummers Academy". In an extended flashback sequence, Mario tells the story of how he and Luigi became plumbers after being flunked by Sergeant Kooperman at the Brooklyn Plumbers Academy.

In the episode "Flatbush Koopa", a Warp Pipe leading to Brooklyn is discovered, and Mario and Luigi, having defeated King Koopa, get to return home. When they get there, they are surprised to see that King Koopa also escaped, and is slowly turning the city into "Kooplyn", as revenge against the Mario Bros. for ruining all of his evil plots. Although they manage to foil King Koopa and lead him back to the Mushroom Kingdom, Mario blows up the pipe with a Bob-Omb, if only so that King Koopa cannot return to Brooklyn. By blowing up the pipe, Mario and Luigi are forced to stay in the Mushroom Kingdom until they can find another way to get home.

The Adventures of Super Mario Bros. 3
In The Adventures of Super Mario Bros. 3, more Warp Pipes leading to the real world had been discovered, making access to Brooklyn much more convenient.

In the episode "Toddler Terrors of Time Travel", Bowser and Kooky try to go back in time to stop the Mario Bros. from going down the drainpipe in Brooklyn, but their plan screws up when the Time Tube turns them, along with Mario, Luigi and Toad into babies.

In "Misadventures in Babysitting", Mario and Luigi accidentally warp into a Brooklyn home, and get suckered into babysitting a brat named Junior, who warps himself to the Mushroom Kingdom in a game of hide and seek.

In "Recycled Koopa", the Koopalings dump their garbage down a Warp Pipe to Brooklyn. As a result, the garbage mutates the people there into Koopa Zombies and turns other creatures into members of the Koopa Troop (e.g. seagulls into Para-Goombas and fish into Spiny Cheep-Cheeps). Mario and Luigi do what they can to clean up the garbage before the entire city, let alone the whole Real World, gets contaminated.

Super Mario World television series
While the location itself does not appear, Brooklyn is mentioned in the Super Mario World animated series episode "Mama Luigi" when Luigi says, "Well, like they say in Brooklyn, early to bed, early to catch the worm. Or is it the bagel?"

Club Nintendo
The story of the Club Nintendo comic "Super Mario: Im Rausch Der Geschwindigkeit" takes place in Brooklyn, where there is a fictional speed limit of 80 "dinosaurpower" Mario is overstepping.

The Nintendo Skyscraper, which appears in the story "Super Mario in Die Nacht des Grauens", is also located "in the heart of Brooklyn".

Super Mario Bros. film
In the live-action Super Mario Bros. film, Mario Mario and Luigi Mario live in Brooklyn, where they run the Mario Bros. Plumbing Service. The bulk of the film takes place in Dinohattan, an alternate-universe version of New York City in a world where humans evolved from dinosaurs.

The Super Mario Bros. Movie
Brooklyn is a setting in The Super Mario Bros. Movie, being where Mario and Luigi originally hail from and run a plumbing business before they arrive in the Mushroom Kingdom through a Warp Pipe. Pauline also resides there, as the mayor of New York City. Notable locations in Brooklyn include Punch-Out Pizzeria, a diner where the Mario Bros. like to spend their time, Castle Burger, and their Mario and Luigi's family apartment.

When Bowser's lair is transported to Brooklyn, the Mario Bros. battle him and the Koopa Troop on the streets.
