Pipe Land

Pipe Maze (known as Pipe Maze or Pipe Land in the English version of the original NES version, alternatively known as Tube City in the Nintendo Power Strategy Guide) is the seventh world in Super Mario Bros. 3. Pipe Maze consists of nine levels, two Fortresses, three Toad Houses, two Spade Panels, a Mushroom King's palace, and two special Piranha Plant levels. The world consists of many islands linked by a confusing network of pipes. The levels in this world often have complex pipe networks within. The kingdom is known to have landscapes, such as plains, deserts, and more, with several pipes. Besides the Piranha Plant denizens, the denizens of the world are implied to be Vikings, due to the King wearing a viking's helmet and overall resembling a nordic viking.

The labyrinth world of Pipe Maze is conquered by Ludwig von Koopa, who turns the king into a Piranha Plant (a Yoshi in the remakes) and all of its islands resemble Warp Pipes.

It was located to the east of Grass Land, and to the west of Iced Land.

This is a wraparound level, meaning if Mario goes out of one side of the screen, he'll reappear on the other. Plenty of pipes are found here along with Piranha Plants and Koopas.

The second pipe in the level leads to an underground pool filled with coins, many of which can only be collected by Frog Mario. There is also a P-Switch in the far left end of the pool. After returning back through the pipe, Mario continues walking to the right and jumps over the pit with a crack in it. After a wooden block and a Nipper Plant, Mario must duck in the highest pipe, then make his way to the right-most pipe, going up it. Afterward, he appears in a valley of pipes, above which are many invisible ♩ Blocks which Mario must hit. Afterward, Mario ducks in the pipe to the right, grabs a power-up, comes out, ducks in the pipe to the left, and finally exits the one on the right. Then he crosses the valley on the newly made bridge of ♩ Blocks; on the sixth Block from the left, Mario can jump extra-high to grab a 1-Up. After that, the lowest pipe from the left of the right wall is the pipe leading to the exit pipe.

This stage is very simple, except for the Lakitu. However, halfway through the level a Starman chain can make this easier. Also, later in the level there is a pipe with unlimited Goombas, which invincible Mario can kill for many 1-Ups. Each of the ? Blocks on the sides of the pipe has a Starman, which can be used to kill some Goombas. Lakitu will then chase Mario.

This water stage introduces Spiny Cheep-Cheeps. Also, this level boasts a huge maze of Jelectros. The Big Bertha and Blooper Nannies also infest the water.

This level is a series of rooms. The first and second have nothing worthwhile, but in the third room, hit all the invisible blocks in the gaps in the floor. Then, at the last gap, jump through. The second pipe from the right has a exit not blocked by a block, and if Mario goes all the way to the left and goes in that pipe, he'll be lead to a power-up. After the pipe, Mario must go left, then fall through the second gap and go through another pipe. As a powered-up Mario, he must smash through the blocks to a pipe, then hop in. In this room, Mario must expose invisible blocks to make a solid path on the top, from platform to platform. Right by the pipe at the end, to the left, is a block with a 1-Up. Mario can then exit through the pipe, go across the other bridge he made, then take one last pipe into the out side.

This stage is optional, but helpful. Mario must adventure over Munchers and all kinds of foliage. If he has a spare Starman, it'll aid him greatly. The smallest pipe at the end leads to a room with a P-Wing.

This nearly-enemy-less castle has a secret. If Mario enters powered-up, he can smash away the fourth row of blocks by the metal block, eventually uncovering a P-Switch that, when stomped, will turn the floor into a coin smorgasbord. There is also a secret room that contains a Tanooki Suit here. The only way to reach Boom-Boom's room is by flying near the left side of the large checkerboard-floor chamber, and entering the pipe hanging from the ceiling.

Only 200 seconds are given to complete this fortress.

This is another wraparound stage, but fairly simple. Mario needs to use the Arrow Lifts to ride on to get through the level while avoiding Spikes and Piranha Plants. If he uses the P-wing in the beginning, Mario can simply fly over the wall and get to the end of the level.

This stage has a line-up of Munchers. Mario needs to use every Starman found in the stage and run across the Munchers to get through the level. He can let the Stars roam for a bit before grabbing them, effectively heightening his invincibility time. Also, it is possible to use a P-Wing to fly over the Munchers.

This stage has more Piranha Plants and Venus Fire Traps. A Starman and/or a P-Wing work great here. There is a Starman in the first ? Block, allowing Mario to weed-whack the plants. Plus, the second walking Ptooie guards a pipe to a secret room, which has a Hammer Suit! Use it to smash Mario's way to the exit, and dodge fire attacks from Venus Fire Traps and Nipper Plants. Mario also finds a Coin Heaven by jumping and hitting a red jump block.

Mario will encounter a Fire Breathing Nipper Plant at the end of World 7-8. There is only one of these Fire Breathing Nipper Plants in the entire game, making it the rarest enemy encountered in Super Mario Bros. 3.

This level is a maze of tubing. There are quite a few secrets, and quite a few baddies. Mario can collect coins by smashing the blocks below them. There are many several rich coin deposits in this stage, but the player should watch the timer.

Hammer Mario can breeze through this befuddling Fortress, but other Marios might have a harder time. Almost all the Fortress enemies are here. There are lava and pipes too. Boom Boom waits at the end as always.

Mario can jump right over the first stretch of Munchers. Cross a field of Munchers using sparsely-placed ♩ Blocks and claim the Super Mushroom prize at the end.

An Anchor is highly recommended, as the Airship can traipse all over the world, and Mario cannot. This Airship has Rocket Engines waiting to singe Mario's rear as he balances on Bolt Lifts. Rocky Wrenches are here too, and Ludwig von Koopa awaits Mario at the end. Mario can tackle him like all his other siblings, but like Roy, he'll paralyze the plumber by jumping around. Additionally, at the end of the airship Mario will get a letter from Bowser, saying "I kidnapped the princess!"

The Adventures of Super Mario Bros. 3
In The Adventures of Super Mario Bros. 3, Pipe Land, which was sometimes referred to as the Pipe Maze, appeared in a few episodes. Underneath Pipe Land is vast underground maze filled with pipes and rivers. It is populated by various enemies such as Thwomps, Boo Diddleys, Venus Fire Traps and even a Boom Boom.

Oh, Brother!: Using the Power Shower, Kooky and Bowser were scheming to wash all the coins floating around in the Pipe Maze into a dungeon where they could collect them. When the Power Shower sprung a leak, Kooky captured Mario by pulling him through the Pipe Maze using his Plumber Pole. Kooky then hypnotized Mario using his Lame Brainer so that he would mindlessly repair the invention. Luigi attempted to swim through the Pipe Maze to rescue Mario, but after a being chased by a Boss Bass, he returned to Toad's House to don a Frog Suit. As Frog Luigi, Luigi eluded all the enemies in the Pipe Maze and found his way to the Koopas' dungeon. After Luigi rescued Mario and defeated the Koopas, the Power Shower was dismantled, and all the stolen coins were returned to the Pipe Maze. Misadventure of Mighty Plumber: In this episode Bowser wanted to rob the Pipe Land Coin Treasury. After Cheatsy brough Mighty Plumber to life from the TV, Bowser tricked him by saying that Mario and Luigi were trying to rob the treasury. Mighty Plumber followed Bowser through Pipe Land's underground maze, keeping Mario and Luigi out of Bowser's hair. After Bowser plundered the vault, he locked Mighty Plumber inside along with Mario and Luigi. With some help assistance from Mario and Luigi, Mighty Plumber escaped, took the coins back, and was returned to the TV. Mario and Luigi later returned the coins to the treasury.

Misadventures in Babysitting: The Pipe Maze was also featured in this episode. Junior, a spoiled child from Brooklyn whom Mario and Luigi accidentally wound up babysitting, found a warp leading to the Mushroom Kingdom. There he quickly befriended Bully, Cheatsy, and Kooky. The Koopalings used Junior as bait to lure Mario and Luigi into a volcano. However, they Koopalings betrayed Junior and tossed him into the Pipe Maze, where he was scared off by various enemies. Eavesdropping on the Koopalings, Mario and Luigi learned about where Junior went, and travelled into the Pipe Maze to find him. At the same time, Kooky began filling the Pipe Maze with lava. However, Mario and Luigi were able to find Raccoon Power, and were able to use it to free Junior from the Pipe Maze.
