静坐罢工

静 = 争 + 青 : Joan of Arc meets the grim reaper in the engine's bathroom. She is scared to death and does not dare to move, so she stands extremely quiet. This time, the grim reaper did not come for her; he just wants to drink from the fountain of youth, which is located in the engine's bathroom.

坐 = 从 + 土 : Zapatista Zebra (zu) sits next to a rubber chicken (从) on a clay (土) bench (mnemonic symbol for 坐) in the observatory's bathroom.

罢 = 去 + 罒 : Beelzebub (b) is on a strike (罢) in the ashram's bathroom (a4). He is not a Sissy though, so he locked his arms in a concrete barrel (去) hanging right under the floor in a net (罒) so he is hard to get at. He will shout at anyone who wants to use the toilet until his demands are fulfilled.

工 = 二 + 丨 : Mnemonic symbol: a steel beam, since 工 looks like the cross section of a steel beam. In front of the engine ((e)ng1), Gitta Giraffe (gu) is doing some hard work: She's stacking a capacitor (二) on a dinosaur bone (丨) on a capacitor (二). She's not very successful, but then she gets the idea to use steel beams (工) as support.
