A conveyor belt is a platform that automatically transports Crash when he is riding on it. They first appear in the original Crash Bandicoot game, in the levels Heavy Machinery and Castle Machinery. They reappear in Crash Bandicoot 3: Warped in the levels Future Frenzy and Gone Tomorrow. In Crash 3, the conveyor belts either have a green or blue color in them, indicating the direction. The ones containing the green color either move forward or to the right, while ones containing the blue color either move backward or to the left. Also, in the secret warp room of Crash 3, there is a conveyor belt transporting lab assistants that can be seen in the background. Conveyor belts also appear in Crash Bandicoot: The Wrath Of Cortex in some factory levels, such as Compactor Reactor. In Crash Bandicoot: The Huge Adventure, conveyor belts appear in Ace of Space, Star to Finish, and Final Countdown.
