表面外膜

表 = 龶 + 𧘇 : Brunhilde (bi) is playing a lead role inside of the aorta (ao3). She is playing a king and therefore richly decorated: there are expensive watches (表) dangling from each of her wrists, and she is wearing a very expensive headdress. Currently she's standing on top of a step ladder and crying out loud for a horse.

面 = 丆 + 囬 : Mnemonic symbol: a spray flask with one of these liquids which make a surface super slippery.

In the anthill's bathroom (an4), Marilyn Monroe (mi) wants to set up a wind wheel (丆) on top of a closet (囬). Just as she tries to fix it she slips and falls down, the wind wheel crashing on the floor. She didn't notice that somebody used a can of non-stick coating (面) on the closet's surfaces (面).

外 = 夕 + 卜 : There's a hole in the wall of the airplane's bathroom (ai4), and from outside (外), a bat (夕) wants to enter. Willy Walrus (w) is very afraid of bats, so he does his best to hinder the bat from entering with a voodoo staff (卜).

膜 = 月 + 莫 : In the observatory's kitchen (o2) the moon (月) and Mozart (莫) are spanning a membrane (膜) as a trampoline for Mahatma Gandhi (m) to jump on.
