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.

Gitta Giraffe (gu) is working a shift in front of the engine ((e)ng1). Her job is to melt dinosaur bones (丨) so that they can be disposed off easily. To melt the bones, she is shorting a huge capacitor (二) with a steel beam (工) which consequently heats up to a bright glow. Using the glowing hot steel beam she can melt the dinosaur bone easily.
