命不久已

命 = 亼 + 叩 : In engine's bathroom, Marilyn Monroe kow tows before a pointed hat. She thinks that this is her fate.

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.

久 = ㇏ + 勹 : Mnemonic symbol: an hourglass.

Joan of Arc (ji) has been waiting for ages (久) for the elephant (勹) to get up from the outhouse's living room (ou3) sofa. She point towards a huge expired hourglass (久) and pokes him with a finger (㇏) to make him finally get up.

已 = ㇖ + 一 + 乚 : Kinda looks like a dredger. Maud Younger wants to dig a tunnel from the space station to earth, so she already used a dredger to dig up the walls just inside the space station. Unfortunately there are a lot of flutes built into the wall, and the dredger is of no use here, so she had to stop. Instead she then has to use a shovel and a sickle to scratch the flutes free and lever them out afterwards.
