力有未逮

力 = ㇆ + 丿 : Mnemonic symbol: a power button.

Li Qingzhao (li) just had a shower in the space station's bathroom (Ø4) and wants to use the hair dryer, but there's no plug, just the bare end of the cable! She uses all her power to build an electricity plug, and for the two pins she uses a plough (㇆) and a banana (丿). Finally she hits a big power button (力) to turn the power on.

有 = 𠂇 + 月 : Mnemonic symbol: confetti.

In an act of revolution, with a pair of scissors (𠂇) Maud Younger (y) is cutting a paper moon (月) into tiny pieces in the outhouse's living room (ou3). There is (有) only confetti (有) left over.

未 = 一 + 木 : Mnemonic symbol: the artist Ai Weiwei. Shortly after finishing a new installation in the Eiffel Tower's bathroom (ei4), Ai Weiwei (未) is imprisoned by Willy Walrus (w), because—out of all places—Ai Weiwei put his new installation right into Willy Walrus's toilet. Ai Weiwei's installation is a Christmas tree (木) with a tiny, slightly tilted flute (一) on top. Ai Weiwei would really, really like to correct the tilted flute, but so far, Willy Walrus has not yet (未) let him out.

逮 = 辶 + 隶 : Don Quixote (d) arrests (逮) the seated scribe (隶) as the scribe is sitting on the royal toilet in the airplane's bathroom (ai4) for stealing the royal gladiator sandals (辶).
