Blade Traps, also known simply as Traps (トラップ Torappu?), are recurring obstacles in the Legend of Zelda series. These spiked traps are situated in the corners of rooms. They generally look like simple boxes, usually gray in color, with sharp spines protruding from all sides. When Link enters a room, he sets off the motion-detecting traps, which fly toward the doorway to impale him with their spikes. This removes the possibility of him remaining in a doorway long enough to assess the situation in a given room. Some Blade Traps instead follow preset paths.
