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.

打 = 丁 + 扌 : Don Quixote (d) got lost in the ashram (a3) and is afraid of being beaten (打). He equips himself with a claw (扌) for the left hand and a nail (丁) for the right hand, ready to beat (打) anyone approaching him.

成 = 万 + 戈 : Mnemonic symbol: a progress bar stuck at 99%.

成 = 万 + 戈 : Charlie Chaplin is queuing at the engine's kitchen, which is blocked by a neuron until the progress bar above shows 100%. Unfortunately it has been stuck at 99% for two hours now. If it doesn't finish soon, Charlie will get completely mad and destroy the neuron himself with his spear.
