择 = 丨 + 又 + 扌 + 二 : Zorro (z) has to select (择) his new weapon between two terrible choices (择) in the elevator's kitchen (e2): there is either a boxing glove (又) or a dinosaur bone (丨).

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.

开 = 一 + 廾 : A bottle opener. Karl Marx is sitting in front of the airplane, begging for money. He's playing a flute and has his bottle opener ready for the next beer, but unfortunately, he'll be carried away, his hands cuffed, soon.
