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.

舟 = 丹 + ⺀ : Mnemonic symbol: 舟 looks like the tower of a yellow submarine. In front of the outhouse (ou1), James II of England (zh) stands next to his yellow submarine (舟) and asks you: will you swallow the blossom (⺀) and continue your quiet life? Or will you swallow the red pill (丹) and follow him on his adventures in the submarine?
