莫不然

莫 = 艹 + 日 + 大 : Mnemonic symbol: 莫扎特, Mozart. Mozart (莫) is giving a concert in the observatory's bathroom (o4). He is sourroundes by sheets of artificial lawn (艹), and since there is none who (莫) is allowed to touch the lawn, it is guarded by a big robot (大). Mahatma Gandhi (m) is in the audience and in the middle of the concert he jumps on the lawn to protest against the sun (日), who is also in the audience, because the sun is responsible for draughts which threaten the farmers. In the end the robot has to carry Gandhi away.

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.

然 = 灬 + 肰 : Robinson Crusoe is grilling some dog meat on his BBQ in the anthill's kitchen, but it's hard to do it correctly because of all the animal rights activists. They think it's not right to grill dog meat.
