The cargo hold and engine rooms of the cruise ship, as well as crew quarters and other areas not intended to be seen by the guests, comprise the bowels. These are the lowest points of the ship, and unlike the well-decorated upper levels, the aesthetic is sparse and functional. The bare metal walls are stained with rust, and low-hanging pipes are common. Given the ship's size, this area falls well below the waterline, leaving ambient noise strange and unsettling, and creating a stifling atmosphere. The cargo hold is full of wooden crates, creating an artificial maze, though most of the crates are empty and those that are not are mostly filled with screws and bolts rendered inoperable by manufacturing defects; these were brought in by the producers to populate the area.
