临 = 刂 + 大 + 囗 + 丨 : In the encampment's kitchen ((e)n2), the robot (大) oversees (临) his army by standing on a huge wooden box (囗). The box is only able to carry his weight because it has been reinforced using a dinosaur bone (丨) acting as a pillar.

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.

儿 = 丿 + 乚 : Mnemonic symbol: "son" (儿) sounds similar to "Sun" like in "Sun Wu Kong", so it's gonna be represented by the monkey king.
