Conveyor Belt

Conveyors (also known as Conveyor Belts ) are platforms found in many Mario games. They are able to carry the player from one place to another without them having to move at all, and can serve as an obstacle or a means to travel faster, depending on the direction the player is heading.

Donkey Kong
In Donkey Kong, conveyors appear in 50m. This level has a series of conveyor belts which run along the second, fourth and fifth floors.

Mario vs. Donkey Kong series
Conveyors are one of the many obstacles the Mini Marios face in the Mario vs. Donkey Kong series, appearing in Mario vs. Donkey Kong 2: March of the Minis, Mario vs. Donkey Kong: Minis March Again!, Mario vs. Donkey Kong: Mini-Land Mayhem!, and Mario vs. Donkey Kong: Tipping Stars. They first appear in Mushroom Mayhem Room 1-7 in March of the Minis, and so on in later levels of the game, and in Mini-Land Mayhem!, they appear mainly in the Teatime Twirl area, serving as the world's main obstacle.

These objects in the screen have two directions to rotate: the left side and the right side. When a Mini Mario goes onto these obstacles, the conveyor belt will glide the toy depending which direction the conveyor belt rotates. The player can't control the Mini Mario going in the opposite direction because the conveyor belt moves in a faster speed than the moving Mini Mario.

The only way that the Mini Marios can glide to the opposite direction is to tap the button that has a symbol of two arrows pointing away from each other with the stylus. In addition, all the conveyor belts in the level switch to its opposite direction. In later levels, there is however more than one button to control all the conveyor belts in the whole level (including violet conveyors).

Super Mario series
Conveyor Belts reappear in Super Mario Bros. 2, Super Mario Bros. 3, Super Mario 64, New Super Mario Bros., Super Mario Galaxy, New Super Mario Bros. Wii, New Super Mario Bros. 2, and New Super Mario Bros. U. In Super Mario Bros. 2, they are only found in World 7-2, where their color is purple/red and enemies aren't affected by it, unlike later games. In Super Mario 64, it makes it's first 3D appearance with its color being yellow and having arrows showing the direction it's pointing in the direction it normally goes. In World Flower-Castle in New Super Mario Bros. 2, there are two Conveyor Belts that can change directions and colors (blue or red) by hitting a yellow switch, one of which appears in the battle against Lemmy.

Conveyor Belts also appear in Super Mario 3D World. However, they only appear in the levels Bullet Bill Base and Captain Toad Gets Thwomped.

Conveyor Belts can be used in Super Mario Maker and Super Mario Maker for Nintendo 3DS, where it's possible to adjust their direction, speed, and length.

Mario & Luigi: Bowser's Inside Story
Conveyors appear again in Mario & Luigi: Bowser's Inside Story, where black-colored ones are found in Bowser Path. Bowser can be seen going against a conveyor when for part of his conversation to the Shy Guys he released from the cage.

Super Smash Bros. Brawl
Conveyor Belts also appear in Super Smash Bros. Brawl, as a Custom Stage Builder part. They are unlocked by creating at least five custom stages.

Yoshi's Woolly World / Poochy & Yoshi's Woolly World
Conveyor Belts appear in World 6-6: Feel Fuzzy, Get Clingy in Yoshi's Woolly World and Poochy & Yoshi's Woolly World, where they are made of the hooks from a hook and loop fastener (colloquially known as Velcro). Because of this, Yoshi can cling onto them as they move (hence the level name), allowing him to access unreachable areas. Burrberts can also be found stuck on Conveyor Belts.
