吴哥城

吴 = 口 + 天 : Mnemonic symbol: the water buffalo from Wu.

Willy Walrus (w) enters the space station (Ø2) with a big mandarin (口) in his hands. The water buffalo (吴) sees it and begins to pant heavily, slightly in panic. Fortunately there is an angel (天) around to calm him down and let him know that it's not the sun he's fearing.

哥 = 可 : Did you know that Godzilla (哥斯拉 ge1 si1 la1, mnemonic symbol for 哥) was the elder brother (哥) of Guy Fawkes (g)? They used to share kebabs (可) regularly sitting in front of the elevator (e1).

城 = 土 + 成 : Again Charlie Chaplin is unable to exit engine. There is a wall of dirt blocking the entrance, and a progress bar showing that it will be removed soon, but the bar seems to be stuck.
