Warp Pipes are a frequent sight in Super Smash Bros. games, hailing from the Mario series.
Mushroom Kingdom has three Warp Pipes, two of which can be entered. A character who enters a Warp Pipe will exit one of the two others randomly, though they will not exit out of one that is blocked.
Luigi's Board the Platforms stage has three platforms contained within large Warp Pipes.
Three Warp Pipes serve as platforms in Yoshi's Island.
During the Mushroom Kingdom stage in Adventure Mode, Warp Pipes appear as checkpoints; if the player is KOed, they will re-spawn at the last Warp Pipe they passed. Additionally, there is one long horizontal Warp Pipe that serves as a platform immediately after the Yoshi ambush.
In Mushroom Kingdom, some Warp Pipes can be seen entering into the pits; however, they are behind the field of play and have no bearing on the characters. However, in a pre-release image of the stage, it appears that Warp Pipes were intended to be used as platforms.
Warp Pipes reprise their role as platforms in the returning Yoshi's Island stage, as well as being present in both versions of Mushroomy Kingdom.
On Mario Bros., four Warp Pipes spawn and move the Sidestepper and Shellcreeper enemies. However, these pipes are not platforms and do not directly affect the fighters.
Warp Pipes appear as both stage elements and a trophy.
Multiple stages contain Warp Pipes as platforms, namely: 3D Land, in which some of the Warp Pipes move up and down; Golden Plains, in both its regular and Ω form; Paper Mario, in which the sole Warp Pipe springs characters upwards; certain variants of Super Mario Maker; Brawl's Mushroomy Kingdom, although only the 1-1 variant appears; and Melee's Yoshi's Island.
Additionally, one of the drawings in PictoChat 2 is a group of warp pipes placed on the floor and just inside the left, uppper and right stage boundaries. These Warp Pipes are notable due to the fact that one can enter them by crouching on top of one, which causes them to exit a different pipe.
Several stages also include Warp Pipes in the background, namely the Ω form of 3D land and the regular form of Brawl's Delfino Plaza and Mario Circuit.
Sometimes Piranha Plants live in them... That's right! I'm talking about those iconic green pipes. World 7 of Super Mario Bros. 3 was actually called Pipe Land. Jump over pipes! Run along pipes! Enter and exit pipes! ...I'm saying there are a lot of pipes.
Jump on top, and then...bloop bloop bloop! Down the pipe! Sometimes, though, they have Piranha Plants inside, so be careful! By the way, did you know that World 7 in Super Mario Bros. 3 is called Pipe Land? It's full of pipes! You sleep in pipes, dream of pipes...Pipes-pipes-pipes-pipes-pipes!
Warp Pipes also appear as platforms in returning stages Mushroom Kingdom, Yoshi's Island, Mario Bros., Mushroomy Kingdom, 3D Land, Golden Plains, Paper Mario, Pictochat 2, and Super Mario Maker. They can also be found in the background of Figure-8 Circuit.
Warp Pipes also appear as a mode of transportation in the world map for Adventure Mode: World of Light, providing travel to different areas.
Pipes are a commonly used element in Mario games, debuting in Mario Bros., which featured pipes on the sides of the playing field from which enemies would emerge. Starting with Super Mario Bros., Mario and Luigi could enter pipes themselves and be transported to another area of the level, although some pipes were purely decorative. The usage of a Warp Pipe as Mario and Luigi's on-screen appearance could be a reference to the beginning of Super Mario 64, where Mario uses one to warp to the garden of Princess Peach's Castle.
