Wall hangings are recurring mirror objects within Tallon IV's Chozo Ruins. They have a highly reflective surface, and their scan states that they do not appear important, suggesting that they are merely decoration. Should Samus look into one, she will see her reflection. However, if she jumps, she is not seen Spin Jumping as in the Metroid Prime 2: Echoes Multiplayer; the animation remains the same as the first jump.
