临时工

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. Just as the robot is about to (临) wave his kitchen knife (刂) into the direction his troops should charge, Li Qingzhao (li) shows up and kicks away the dinosaur bone, causing the robot to fall off his box.

时 = 寸 + 日 : Mnemonic symbol: a giant pocket watch.

The sun (日) asks Sherlock Holmes (sh) out for a coffee in the space station's kitchen (Ø2). Looking at his pocket watch (时), Sherlock sees he has time, winks and "thumbs up" (寸).

工 = 二 + 丨 : Mnemonic symbol: a steel beam, since 工 looks like the cross section of a steel beam. In front of the engine ((e)ng1), Gitta Giraffe (gu) is doing some hard work: She's stacking a capacitor (二) on a dinosaur bone (丨) on a capacitor (二). She's not very successful, but then she gets the idea to use steel beams (工) as support.
