大便秘结

大 = 一 + 人 : The big (大), huge (大) robot (mnemonic symbol for 大) is working out in the ashram's bathroom (a4). He's lifting a flute (一) to which Don Quixote (d) and Neanderthal man (人) are clinging.

便 = 亻 + 更 : "Handy" is a German word for "mobile phone", so that's what I will represent this character with.

便 = 亻 + 更 : Brunhilde lost her mobile phone! When Rosa Luxemburg helps her to find it by calling Brunhilde's phone, they discover that it must be inside the snake that ate an elephant which is lying in the anthill's bathroom. Together they open the snake's mouth to see wether they can find it.

秘 = 必 + 禾 : Khubilai Khan (必) enslaved Marilyn Monroe (mi) and now she has to serve as his secretary (秘). She has to bring him his cereals (禾) every morning into the space station's bathroom (Ø4), because Khubilai cannot do his poo-poo before he had his cereals.

结 = 吉 + 纟 : The silk worm and Joan of Arc are in an awkward situation. The giant has pulled the worm so long that she's long enough to tie Joan of Arc to one of the pillars of the elevator's kitchen, and to even make a knot.
