不甘於

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.

甘 = 二 + 卄 : Mnemonic symbol: 甘 just looks like a cow's head to me.

In front of the anthill, Guy Fawkes wants to drink the cow's sweet, sweet milk. He already organized a capacitor as electric shocker. The cow is not willing to surrender at all, though: she is ready to defend herself with a double axe.

于 = 亅 + 二 : Mnemonic symbol: prepositions (in, at, on, to, ...) are what glue the sentence together. Honey is as sticky as glue, so I'll represent 于 by a honey jar.

Yu the Great (于) was assigned to repair the electronics of the space station's kitchen (Ø2), but instead he was snacking honey from a honey jar (于). Unfortunately his capacitor (二) got stuck in the honey and now he has to use a crowbar (亅) to lever it out.
