Conveyor Belt

Conveyor Belts (or simply conveyors) 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, Conveyor Belts appear in 50m. This level has a series of conveyor belts which run along the second, fourth and fifth floors.

Super Mario Bros. 2
In Super Mario Bros. 2, conveyor belts are only found in World 7-2, where their color is purple/red and enemies are not affected by it.

Super Mario Bros. 3
Conveyor belts reappear twice in Super Mario Bros. 3, in and in, where they appear black and white. They stop moving while a Switch Block is active.

Super Mario World
Diagonal conveyor belts appear in Super Mario World, present inside Morton's Castle, Ludwig's Castle and Larry's Castle.

Super Mario Land 2: 6 Golden Coins
Conveyor belts reappear in Super Mario Land 2: 6 Golden Coins, where they have the appearance of blocks with arrows indicating the direction they are moving in. They appear in the levels Fiery Mario–Special Agent and Final Boss: One Mighty Mouse! of the Macro Zone and in Beware: Jagged Spikes of the Mario Zone.

Super Mario 64 / Super Mario 64 DS
In Super Mario 64, conveyor belts make their first 3D appearance, this time colored yellow with arrows showing the direction they are moving in. They appear only in Tick Tock Clock. Conveyor belts reappear in the remake Super Mario 64 DS, fulfilling the same purpose.

New Super Mario Bros. series
Conveyor belts are featured in many levels in New Super Mario Bros., New Super Mario Bros. Wii, New Super Mario Bros. 2, and New Super Mario Bros. U. In these games, they are commonly used to move Iron Blocks. 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.

Super Mario Galaxy
Conveyor belts reappear in Super Mario Galaxy, in Toy Time Galaxy.

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

Super Mario Maker / Super Mario Maker for Nintendo 3DS / Super Mario Maker 2
Conveyor Belts return as course elements in Super Mario Maker and Super Mario Maker for Nintendo 3DS, where their speed can be adjusted by shaking them. Their direction and length can also be changed. Pressing a P Switch causes the Conveyors to stop moving. In Super Mario Maker 2, Conveyor Belts can be placed diagonally, acting as Slopes. Additionally, a new type of Conveyor Belt is introduced that is toggled by ON/OFF Switches, switching direction when one is activated.

Wario Land: Super Mario Land 3
In Wario Land: Super Mario Land 3, conveyor belts appear infrequently in early levels. They first appear in Course No.12 in Mt. Teapot, then later in Courses No.15 and 16 of Sherbet Land. They are absent until Course No.27 in the SS Tea Cup, though here, they are only ceiling decorations.

Wario Land II
In Wario Land II, they are a little more common, appearing Escape from the factory!, Into the factory!, Move through the water!, Awaiting Syrup!, and The Final Battle!!. The direction they move can be changed with a switch.

Wario Land 4
In Wario Land 4, appear in The Curious Factory and 40 Below Fridge, working as before.

Wario Land: Shake It!
Finally, in Wario Land: Shake It!, there are three types of conveyors; red, which hold their direction, blue, which can be reversed with Certainty Switches, and green, which can be turned off with their own switches. They appear in a large number of levels.

Mario vs. Donkey Kong series
Conveyor belts are frequent mechanisms used by Mario and Mini toys throughout the Mario vs. Donkey Kong series. Their design in these games generally features a row of arrows running along their body, pointing in the direction in which the conveyor belt is currently moving. With the exception of their appearance in Mario and Donkey Kong: Minis on the Move, they are always horizontally oriented and run either left or right. Conveyor switches often accompany conveyor belts, allowing the player to change the direction of all conveyor belts in the level in order to solve puzzles. Conveyor belts can carry enemies, including fallen Thwomps, in their assigned direction.

Mario vs. Donkey Kong
In Mario vs. Donkey Kong, conveyor belts are first found in Level 1-4 of Mario Toy Company. Their color scheme depends on the world they appear in. Their main purpose is carrying Mario through tight passages while he crouches. Conveyor belts can also be used to ferry keys into more accessible areas near the exit. They also significantly impede Mario's walking speed if he runs against them, although he can still successfully walk in their opposite direction. This is the only game in the series where conveyor belts are semi-solid, meaning that they can be jumped on from underneath.

In levels with conveyor belts starting with Level 5-1, Mario often comes across Direction Switches, which he can jump on and press to reverse the direction of all conveyor belts in the level. Each Direction Switch has two red light bulbs on its sides, which alternate whenever the Direction Switch is pressed to signal a change in direction.

Mario vs. Donkey Kong 2: March of the Minis
Conveyor belts appear in Mario vs. Donkey Kong 2: March of the Minis, being introduced in Room 1-7 of Mushroom Mayhem. In this game, they appear as dark blue, and their arrows resemble > and < symbols rather than triangles. If a Mini approaches a conveyor belt moving in its direction, Minis will continue to move in the conveyor belt's direction while remaining idle. However, if a Mini approaches a conveyor belt moving in the opposite direction to its own, it will simply turn around. If a Mini falls onto a conveyor belt from above, it will automatically move in the conveyor belt's direction. Minis cannot be swiped to change their direction while on a conveyor belt. Many levels with conveyor belts also feature conveyor switches, which can reverse the direction of all conveyor belts in a level when tapped with the stylus.

Mario vs. Donkey Kong: Minis March Again!
Conveyor belts appear in Mario vs. Donkey Kong: Minis March Again!, functioning identically to their previous appearance. They are introduced in Room 3-2 of Magnet Mania. Magnet Mania also features a tutorial level that showcases the conveyor belt.

Mario vs. Donkey Kong: Mini-Land Mayhem!
Conveyor belts also appear in Mario vs. Donkey Kong: Mini-Land Mayhem!. They are the main focus of Teatime Twirl, which also marks the debut of Purple Conveyors. Standard gray conveyor belts are called Gray Conveyors to distinguish them from Purple Conveyors. Gray Conveyors cannot be moved.

Instead of being fixed in place like Gray Conveyors, Purple Conveyors can be drawn between any two purple rivets using pieces acquired in a level. Conveyor Switches affect the Purple Conveyors in the same way as Gray Conveyors. After Teatime Twirl, both Gray Conveyors and Purple Conveyors continue to appear frequently throughout the game.

Mario and Donkey Kong: Minis on the Move
Conveyor belts, known as conveyors, appear in Mario and Donkey Kong: Minis on the Move. In this game, conveyors are tiles which appear on a grid, and can carry a Mini in any of the four cardinal directions.

Mario vs. Donkey Kong: Tipping Stars
Both Gray Conveyors and Purple Conveyors reappear in Mario vs. Donkey Kong: Tipping Stars, where they are introduced in Runaway Warehouse. They function identically to their appearance in Mario vs. Donkey Kong: Mini-Land Mayhem!.

Donkey Kong Jungle Beat
In Donkey Kong Jungle Beat, vertical conveyors appear in the Clock Tower, moving up to assist Donkey Kong with Wall Jumps.

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.

Mario Kart Wii
Conveyor Belts make their debut in the Toad's Factory course from Mario Kart Wii. The arrows and colors on the conveyor belts reveal which direction they are going in. Thus, the player will become faster while driving on green conveyor belts going forward. However, driving on backward yellow conveyor belts will slow down the player. Item Boxes and crates can be found on these conveyor belts.

Mario Kart 8 / Mario Kart 8 Deluxe
In Mario Kart 8, conveyor belts appear as trickable objects in Sunshine Airport. They are colored black here. They also appear in Rainbow Road, where they have the same purpose as in Mario Kart Wii, though the color of the backward conveyor belts are red instead of yellow.

Conveyor Belts later appear on the escalators of and in  in Mario Kart 8 Deluxe, with the arrows in the former now being bigger.

Mario Kart Tour
In Mario Kart Tour, Conveyor Belts appear on DS Peach Gardens T, Wii Coconut Mall, Singapore Speedway 2 and RMX Bowser's Castle 1, where they serve the same function as before. In Singapore Speedway 2, ramps can be found on the conveyor belts, similar to Mario Kart 8's Rainbow Road.

Mario & Luigi: Bowser's Inside Story / Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey
Conveyor Belts appear again in Mario & Luigi: Bowser's Inside Story and its remake, where they are composed of black cylinders. They are found in Bowser Path, Bowser's Castle, and Peach's Castle, where the latter two locations also feature Fawful-like generators that indefinitely spawn pairs of Bob-ombs moving in lockstep across Conveyor Belts; the Bob-ombs can be avoided by jumping or using a Body Slam. Bowser can also be seen going against a conveyor belt for part of his conversation to the Shy Guys he released from the cage.

Mario & Luigi: Dream Team
Conveyor Belts also appear in Mario & Luigi: Dream Team, where they are exclusively found in certain areas of the Dreampoint in Dreamy Wakeport. If the "fast" setting of Luiginary Speedometer is activated, Mario will be able to effortlessly run against the direction of Conveyor Belts.

Yoshi's New Island
Conveyor Belts are present in Yoshi's New Island in the level Hotfoot Hurdle. They are rather short and floating above lava. They run left (as signified by the three green arrows displayed on them) to make it more difficult for Yoshi to advance to the right. Conveyor Belts are usually placed in rows or one above the other.

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 (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 are often found stuck to Conveyor Belts and carried by them.

Paper Mario: Color Splash
Conveyor Belts in Paper Mario: Color Splash, take the form of green flooring attached to paper rolls. They appear in the Crimson Tower, where enemies such as Goombas and Shy Guys walk on them. Mario can hit one of the Conveyor Belts from below to knock off the Shy Guys running on top of it. Unlike in other games, these Conveyor Belts are not reversible and have a set speed. In Black Bowser's Castle, three large conveyor belts lead into a large mixer of black paint. Paint Guys stand on these, dump their paint in, and then stick to the backside of the conveyor belt. Mario holds Huey above his head and boards the conveyor belt, causing a Snifit to let him pass.
