尾闾骨

尾 = 尸 + 毛 : Willy Walrus (w) knows that there is a ghost (尸) in the Eiffel Tower (ei3), but he cannot see it, so he set up a trap: he put a lot of sticky hair (毛) everywhere, and eventually the hair stuck to the ghost's tail (尾). Now that Willy Walrus can see where the ghost is he is able to drive it out.

骨 = 冎 + 月 : Gitta Giraffe (gu) is performing some dark rites in the space station (Ø3). She 3D printed a whole skeleton (骨) including skull (冎) and is trying to make it come alive under a full moon (月), citing from the Necronomicon.
