一夕数惊

Maud Younger (y) forgot her keys to the space station (Ø1), all she brought outside was her flute (一). She has no choice but to crash the door with the giant flute.

Mnemonic symbol: this character looks a bit like a bat, and bats come out of their caves at dusk. I could see the upper left 丿 as part of the bat's right wing, ㇇ as the body/head and 丶 as the eye of the bat.

Xi Shi (xi) goes out for a space walk in front of the space station (Ø1) in the evening (夕), where she observes a space bat.

数 = 娄 + 攵 : Sheldon Shrimp (shu) occupied a lunar mansion (娄) inside of the space station (Ø3) although he knows that it is to be torn down. Outside of his lunar mansion the construction (or rather destruction) workers are already counting (数) down from ten. When they count (数) zero, they will start taking down the whole thing with their sledgehammers (攵).

惊 = 京 + 忄 : Somebody set off engine's alarm in the middle of the night and Joan of Arc arrives in a rush to scare away any intruder with a flail. She was in such a rush and so tired though that she forgot to put on her pants and arrives in front of the engine just wearing ridiculous underpants which feature a pattern of berets, mandarins and daisies.
