世襲君主國

世 = 廿 + L : Mnemonic symbol: the WTO or WHO.

Sherlock Holmes (sh) is cleaning a flower pot (廿) under the shower of the space station's bathroom (Ø4) with a loofah (L) because he didn't quite understand a poster next to the shower from the WHO (世) explaining dangers arising from different germs.

In this case, L is for loofah.

袭 = 衣 + 龙 : Marie Curie (xi) and the dragon (龙) are taking part in a reenactment just inside the space station's entrance (Ø2). They celebrate Scottish wrestling by wearing kilts (衣) and attacking (袭) each other using awesome moves.

君 = 口 + 尹 : Mnemonic symbol: 马天君 (see example sentences).

In front of the encampment, 马天君, the system administrator and Zeus all share a mandarin.

主 = 丶 + 王 : Julian Giant Squid (zhu) is playing cards with Martin Luther King (王) in the space station (Ø3). It's Martin Luther King's turn, and he holds a petal (丶) in his hand high above his head: it's his trump card, and on it depicted is the Lord (主) himself.

国 = 囗 + 玉 : Mnemonic symbol: a nation's flag. Let's say the Chinese flag.

In the observatory's kitchen (o2) Gitta Giraffe (gu) is practising her ballet performance. She got a whole crate (囗) full of jade bracelets (玉) and flags (国) and fixed one flag to each jade bracelet. This makes a perfect combination for throwing the ring with the flag waving behind it and catching the ring again after a few pirouettes.
