Toxic-Switch of Danger is the Metal Cap level in Super Mario 74, as well as the first secret level accessible in the hack. It is small room filled with toxic air. There are many holes in the floor, some tall pillars, as well as platforms surrounding the walls. At the back is a section of raised ground, where the Metal Switch is found. When in this course, use the Lakitu cam, as the Mario cam is horrible. This level is reached from a warp pipe that is located in the first overworld, Valley of the Toads. There is a wide river that leads into a tunnel at the end. In this tunnel, there is a wall with the pipe leading here on it. There is also a useful sign outside warning the player of how the Mario Camera does not work when in toxic air.
