There is a fire-spitting Furnace located under the trapdoor in the room left of the main area of the Attic, Basement and Beyond Nightmare
. If Ned gets in its way while it's spitting fire balls, he'll get burned, and there are also rats which appear and are burned by the fire if it hits them, as well. Both the fire and the rats come out at random intervals. In the basement, there will be an exit to the Bathroom Nightmare on the left and on the right, a room (which the rats come out of) that
will warp you back out through a phonograph.
