不惜一戰

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.

惜 = 忄 + 昔 : NASA ordered Marie Curie (xi) to do an experiment for them in front of the space station (Ø1). They are spending 2000000000 bucks to see what happens when you crush a milk shake (昔) with a flail (忄) in outer space. Marie Curie thinks it is a pity (惜) and would rather drink her cherished (惜) milk shake rather than crush it.

战 = 占 + 戈 : James II of England (zh) prepares to fight a war (战) in the anthill's bathroom (an4). He has a spear (戈) as a weapon and a yellow umbrella (占) as shield, following his hero Leonidas.
