域

域 = 土 + 或 : Yu the Great (yu) and Osvaldo Farrés (或) have been working in the space station's bathroom (Ø4) for several days now. Their task is to classify different kinds of mud (土) and build a mud taxonomy (域). Most of the time they slack off and play games through the LAN (域) instead, though.

土 = 十 + 一 : Tommy Turtle (tu) wants to fix a cross (十) on a flute (一) in the space station's living room (Ø3). He uses dust and clay (土) to hold them together.

或 = 一 + 口 + 戈 : In observatory's bathroom, Osvaldo Farrés plays his famous song "Quizás, Quizás, Quizás" (Perhaps, Perhaps, Perhaps) on a flute. Helga Horse listens and doesn't know whether she should maybe give him her mandarin as reward, or perhaps stab him with a spear.
