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 (坐) next to a rubber chicken (从) on a clay (土) bench (mnemonic symbol for 坐) in the observatory's bathroom (o4).

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.

动 = 云 + 力 : Doggy Dog notices a lot of smoke when he enters engine's bathroom. Instead of thinking long, he acts quickly and moves to push the fire alarm button.
