Clear Pipe

Clear Pipes are pipes that make their debut in Super Mario 3D World. Like Warp Pipes, they are used for traveling distances too far for a normal jump to reach. Unlike Warp Pipes, however, Clear Pipes are transparent, and a player can change direction while in one. Additionally, players automatically enter vertical Clear Pipes without having to press a button.

Clear Pipes were conceived after the director of Super Mario 3D World, Koichi Hayashida, wondered what Mario did in Warp Pipes.

While traveling through Clear Pipes, Mario and the other playable characters cannot use any attacks like on ground. Some enemies, such as Goombas and Koopa Troopas, can travel through Clear Pipes, and are automatically defeated when collided with while inside a Clear Pipe. However, there are certain obstacles found within Clear Pipes that damage the playable characters upon contact, as is the case with mines and the fireballs produced by Fire Bros or Fire Piranha Plants. While inside Clear Pipes, fireballs can be destroyed by other fireballs or nearby red POW Blocks from outside the pipes. Coins, Green Stars, and other objects can also be found either moving or stationary inside these pipes.

A cannon variety of Clear Pipes also appears. These ones are similar to Launch Stars and Sling Stars from the Super Mario Galaxy games, as they launch the player to another part of the level. Some of these pipes require the player to manually press to launch themselves out of the cannon.

All of the game's worlds, with the exception of the special worlds, are connected through Clear Pipes. Once a Sprixie Princess is saved from the castle at the end of a world, she constructs a Clear Pipe leading to the next world.

In the Bowser's Fury campaign of Super Mario 3D World + Bowser's Fury, Clear Pipes are the main gimmick of Pipe Path Tower. In this area, Mario has to travel through different Clear Pipe paths to reach the top to collect a Cat Shine. Blue Coins and Cat Shine Shards can also be found inside Clear Pipes.

Super Mario Maker 2
In Super Mario Maker 2, Clear Pipes appear as course elements for the Super Mario 3D World style. Like in the original game, Mario can shoot fireballs into them, and enemies such as Goombas and Koopa Troopas can travel through them as well. However, entering vertical ones requires using, unlike in the original game. If both ends of a Clear Pipe are blocked while the playable character is inside, the playable character will be trapped and lose a life.

Captain Toad: Treasure Tracker
Clear Pipes reappear in Captain Toad: Treasure Tracker and its Nintendo 3DS and Nintendo Switch ports, acting the same as in Super Mario 3D World. Their cannon variety also reappears.

Mario Strikers: Battle League
In Mario Strikers: Battle League, Clear Pipes are a type of goal post as part of stadium customization.

The Super Mario Bros. Movie
Clear Pipes appear in The Super Mario Bros. Movie as one of the methods of transportation on the grounds around Peach's Castle. Toad introduces them to Mario as "the only way to fly, man". As Mario draws near the entrance of a Clear Pipe to admire it, he gets violently sucked in and lurches through it as he is slid along.
