Warp Pipe

The Warp Pipe is one of the main modes of transportation of Mushroom World. Generally speaking, a Warp Pipe is a pipe that doesn't always appear to be connected to a second pipe physically, although traveling through it will transport the traveler to the other end. In many cases, Warp Pipes can be used to cross great distances (and even worlds) instantly, while some pipes don't even work. The size of Warp Pipes can vary greatly. While some are too narrow for a human to enter, others are large enough for Bowser's Doomship to travel through. They are traditionally green, but have appeared in many colors in lesser numbers over the years.

''Mario Bros.
Warp Pipes first appeared in the arcade game Mario Bros.. Enemies would emerge from these pipes and attack Mario and Luigi.

Super Mario series
Warp Pipes have appeared in nearly every Mario game since, although Super Mario Bros. 2 temporarily replaced them with Vases. These pipes were first used for transportation in Super Mario Bros.. Some even led to underground levels and mini-levels.

In Super Mario World, some warp pipes acted as mini-cannons, shooting Mario or Luigi high in the air. This feature was also kept in New Super Mario Bros. Also, if Mario or Luigi use the Mega Mushroom, they can kick the pipe, move it in if it is horizontal, or Ground Pound it to make a raised pipe lower to ground level. If Mega Mario or Luigi destroys a pipe, then they cannot go down the pipe anymore. Mini Warp Pipes were introduced here in New Super Mario Bros.: they are tiny Warp Pipes half the size of a regular Warp Pipe, that required Mario or Luigi to use a Mini Mushroom to get tiny so they could enter. Inside these Mini Warp Pipes, Star Coins could usually be found. There are also red and yellow pipes, and some of them expel air when they are underwater to push Mario.

In Super Mario Galaxy there are two kinds of pipes. The classic, green ones, which usually, but not always, disappear after Mario enters them, and orange pipes, which can always be re-entered.

''Nintendo Comics System
The Nintendo Comics System comic, "A Mouser in the Houser" seemed to imply that the Mousers constructed the Warp Pipe system.

''Super Mario Adventures
In Super Mario Adventures, they appeared as the mode of transport between the Mushroom Kingdom and the lands surrounding Yoshi Village. On their first trip through the Warp Pipe Bowser had traveled through, Princess Peach and her followers ended up at a different location from where Mario and Luigi emerged. The narration stated that Mario and Luigi "hooked up with the wrong connection somewhere," implying that not all Warp Pipes lead solely to one other location.

Mario Kart series
In the Mario Kart series, Warp Pipes (usually referred to as simply Pipes) appear as simple obstacles on the courses, especially on the Mario Circuits. On some occasions, mostly in Mario Kart: Double Dash!!, the player can enter a pipe and get warped to another area, mainly used for collecting item boxes.

Mario Party series
Warp Pipes are also items that appear throughout the Mario Party series.

''Mario Party 4
Starting with Mario Party 4, Warp Pipes became an item used for transportation on the board. Whoever used it switched places with another player on the board via roulette. This made it successor of the Warp Block.

''Mario Party 5
In Mario Party 5, it became a Capsule, where it could be thrown to a space on the board, or used on the player for 10 coins. It's effect was still the same as from Mario Party 4.

''Mario Party 6
In Mario Party 6, it became an Orb that players could only use on themselves, but for free (it costs 10 coins at the Orb Shop, though). Again, effect was still the same.

''Mario Party 7
In Mario Party 7, the effect was changed to a roadblock form, where opponents who passed by the space containing the orb were caught by the Warp Pipe, and were sent back to the space he/she was at when their turn started.

Mario Party DS
In Mario Party DS, they appear when a player reaches a shop space and decides to go in. Warp Pipes are also used as a item but it is named a Star Pipe and allows the owner of the item to go to the Star.

Paper Mario series
In the Paper Mario series, Blue Pipes can also take Mario to different places and locations. In Paper Mario and Paper Mario: The Thousand-Year Door, pipes to different locations that Mario previously visited can be unlocked in the Toad Town Tunnels and Rogueport Sewers respectively. In both games the pipes are blue instead of the general green pipes. Super Paper Mario also features smaller warp pipes, similar to those found in New Super Mario Bros. The player has to use Dottie to shrink Mario, so he can enter them. Generally, warp pipes will have some sort of special appearance to fit in with their locations; for example, the pipe in the picture at left is pixelated to fit in with its location in the Bitlands. Likewise, the warp pipes in Boggly Woods seem to be made of wood; additionally, they will usually have a hole in the side so that Punies can use them more easily.

''Mario & Luigi: Superstar Saga
In Superstar Saga, 9 green Warp Pipes allowed Mario and Luigi to travel the Beanbean Kingdom faster. In order to warp to one of these pipes, Mario and Luigi had to have entered it before.

''Mario & Luigi: Partners in Time
During the events of Mario & Luigi: Partners in Time, special blue Warp Pipes required Mario, Luigi, Baby Mario, and Baby Luigi to stand on them in order to activate them. Also, when Mario and Luigi were separated from Baby Mario and Luigi, one of the brothers could jump up and hit a warp pipe box, out of which a miniature pipe came and planted itself in the ground. It would then grow to the size of a normal pipe allowing the brothers to jump in and be reunited with the babies. However, these pipes were one use only and disappeared as soon as the brothers jumped through them.

Wario Land series
Warp Pipes are also present in three games of the Wario Land series, namely Wario Land 3, Wario Land 4, and Wario Land: Shake It!. They work exactly like their counterparts from the Mushroom Kingdom, with the distinction that they don't contain enemies. The Golf Minigame in Wario Land 3 must be accessed through a Warp Pipe. In addition, the slots in the "load file" screen of Wario Land: Super Mario Land 3 bear a resemblance to Warp Pipes.

Trivia

 * A green pipe is an exclusive item in two games in the Animal Crossing series. In the Nintendo GameCube game, Animal Crossing, it is a green warp pipe that makes the warp pipe sound when you touch it. In Animal Crossing: City Folk, it has a Piranha Plant inside that moves up and down. The Piranha Plant will stop moving if the player taps it once again after activating it.
 * Warp Pipes were also featured as Easter Eggs in the game Advent Rising.
 * In the game Captain Rainbow, Warp Pipes appear and are used the same way. They can be green, yellow or pink and have the original Super Mario Bros. sound when using them.
 * The wastebaskets in Pokémon Diamond and Pearl look like green Warp Pipes.
 * In The Simpsons Game, there is a whole level based off other video games. In multiple parts of the level, the characters have to jump into a Warp Pipe to advance further into the level.
 * In Super Paper Mario, when the player uses a Warp Pipe, instead of normally going straight down, the player's character will split into several small squares which will then go down the pipe and re-assemble at the other end.
