银屑病

银 = 艮 + 钅 : Maud Younger spotted a large silver sphere hanging above the entrance to the encampment. She wants to have it and repeatedly throws a golden harpoon at it; to retract the harpoon she uses a chewing gum which she attached to the harpoon, so that it expands to a long rope as she throws the golden harpoon at the silver sphere.

屑 = 尸 + 肖 : Marie Curie (xi) and the little prince (肖) are frequently visiting a ghost (尸) in the elevator's bathroom (e4). The ghost is feeding on their dandruff (屑), therefore it's a win-win situation for all of them, but secretly they feel it beneath their dignity (不屑).

病 = 丙 + 疒 : In engine's bathroom Brunhilde is proudly inspecting her bronze medal. She got it in a contest about having the craziest sickness by painting a colorful rash on her face.
