月球车

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.

球 = 求 + 王 : Martin Luther King and the Queen of Hearts are playing with a globe beach ball in the outhouse's kitchen. They put a service request bell just between them and bounce their beach ball off of it with a loud "DING".

车 = 七 + 十 : Charlie Chaplin (ch) is parading in a cabriolet (mnemonic symbol for 车) in front of the elevator (e1), because he wants to establish his new cult. Like all successful leaders, he takes the carrot-and-stick approach: In one hand he's waving with a seven-branched laser sword (七), in the other one he's waving with a cross (十).
