Blue pipe

The blue pipe, originally known as Pipe, is a pipe item found in Mario Pinball Land. These items can help Mario from losing a life or from leaving the area Mario is supposed to be. They usually appear when the player ventures into a new area as they appear between the flippers the player controls. It can be obtained by buying it from Toad, or hitting a ? Block.

In Paper Mario, they are found in the Toad Town Tunnels in which they can lead to several other areas in an instant. These areas include:
 * Goomba Village, Koopa Village, Dry Dry Outpost: found just to the west of the entrance and needs a Blooper fight to unlock, accessible after getting the Super Hammer in Chapter 2
 * Boo's Mansion: found in the west of the second sublevel and needs fighting with three Dark Koopa groups, accessible after getting the Super Boots in Chapter 3
 * Lavalava Island: found beyond the river of the second sublevel and needs a Blooper fight to unlock, accessible after getting Sushie in Chapter 5

They return in Paper Mario: The Thousand-Year Door where they appear in the middle of Rogueport Sewers sublevel 2 to serve as shortcuts to Petalburg, Boggly Woods, Keelhaul Key, and Poshley Heights. The first two require the Super Hammer, and the last two requires the Ultra Hammer. There is also a differently colored blue pipe that leads to Fahr Outpost. They also appear in Super Paper Mario, where they are built by Welderberg. There are three in the game: One leads to Flipside's B2F, one to Flopside's B2F, and one to Flopside from Flipside (and vice versa). Each is accessible on the second floor of both cities.
