Pipes are used throughout the robot factory for transportation of acid from one location to another. No matter what size they are, acid is transported through them. Some are seen partially outside stone platforms, while some are seen going into platforms. Often seen partially coming out of stone platforms are red pipes, sometimes with a leak in them.
The player may find parts of the robot factory with platforms made up of many big metal pipes, and sometimes a metal pipe pouring liquid into a pool of acid. Pipes are seen in the background of Toxic I, as well as make up a fence around the second robot factory in Toxic II.
