Conveyor Belt

Conveyors (also known as Conveyor Belts) are one of the obstacles that the Mini Marios face during the events of the Nintendo DS video games, Mario vs. Donkey Kong 2: March of the Minis, Mario vs. Donkey Kong: Minis March Again!, and Mario vs. Donkey Kong: Mini-Land Mayhem!. These objects first appeared in Mushroom Mayhem Room 1-7 in March of the Minis, and so on in later levels of the game. They appear mainly in the Teatime Twirl area of Mini-Land Mayhem!, serving as the world's main obstacle.

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
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, New Super Mario Bros., New Super Mario Bros. Wii, New Super Mario Bros. 2, and New Super Mario Bros. U. In World Flower-Castle in New Super Mario Bros. 2, there are certain Conveyor Belts that can change directions and colors by hitting a yellow switch. This Conveyor Belt also appears in the battle with Lemmy.

Conveyor Belts also appear in Super Mario 3D World. However, they only appear in the level 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 and speed.

Super Smash Bros Brawl
Conveyor Belts also appear in Super Smash Bros. Brawl, as a Custom Stage Builder part. They must be 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.
