Conveyor Belt

Conveyors 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.

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 toy 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 (violet conveyors).

Super Smash Bros Brawl
Conveyor Belts also appear in the Wii video game Super Smash Bros. Brawl, as a Custom Stage Builder part. They must be unlocked by creating at least five custom stages.
