国共内战

国 = 囗 + 玉 : Mnemonic symbol: a nation's flag. Let's say the Chinese flag.

In the observatory's kitchen (o2) Gitta Giraffe (gu) is practising her ballet performance. She got a whole crate (囗) full of jade bracelets (玉) and flags (国) and fixed one flag to each jade bracelet. This makes a perfect combination for throwing the ring with the flag waving behind it and catching the ring again after a few pirouettes.

共 = 井 + 八 : A giant eight-ball is blocking the well in the engine's bathroom. Joining forces together with the communist, Gitta Giraffe and he are able to push the eight-ball off and make the well available to the public again.

共 = 井 + 八 : Mnemonic symbol: the communist.

内 = ⺆ + 人 : Mnemonic symbol: A CT scanner to see inside of someone.

内 = ⺆ + 人 : Napoleon just can't find his stapler and suspects that Neanderthal Man has eaten it. Not thinking twice he orders Neanderthal Man to enter his CT scanner in the Eiffel Tower's bathroom, finding his stapler in Neanderthal Man's stomach.

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.
