形影不離

形 = 开 + 彡 : Marie Curie (xi) is modding her fake Santa Clause beard (彡) into a new shape (形). With a bottle opener (开) she carves the beard in the engine's kitchen ((e)ng2) so that it gets a fractal (形) shape (形).

影 = 彡 + 景 : Maud Younger (y) wants to watch a movie (影) inside of the engine ((e)ng3), but only men are allowed. She doesn't bounce back but instead, being a suffragist, puts on a long, fake Santa beard (彡). She enters to find that the whole movie consists of a still frame of a bonsai tree, a landscape in a pot. Back in the days, the script writers were not so experienced it seems.

不 = 丆 + 卜 : Bruno Bear (bu) is setting up a wind wheel (丆) with a voodoo staff (卜) in the space station's bathroom (Ø4). He also puts a "forbidden" sign (mnemonic symbol for 不) on it, to make clear that it may not (不) be stopped.

离 = 亠 + 凶 + 禸 : Mnemonic symbol: from 离心机 or 离心分离机, a centrifuge.

离 = 亠 + 凶 + 禸 : Li Qingzhao is about to leave the space station. As a souvenir she put her beret in the space station's centrifuge and got a demon mask out. Angrily she tramples on the demon mask because what she wanted was a nice and modern hat.
