月 = ⺆ + 二 : Yu the Great (yu) is modelling a moon (月) in the elevator's bathroom (e4). He uses a stapler (⺆) to staple a lot of capacitors (二) together to form a moon shape, while the real moon is sitting for him.

鬲 = 𠮛 + 冂 + 丷 + 丅 : Guy Fawkes (g) is cooking an advanced recipe—which he is reading from an ancient scroll (𠮛) he found—in the elevator's kitchen (e2). He already set up an iron cauldron (鬲).
