曲线救国

曲 = 囗 + 卄 : Mnemonic symbol: a harp. Cupid (qu) is playing a harp (曲) in the space station's living room (Ø3). He's sitting on a big enclosure (囗), playing the harp (曲) and wielding a double axe (卄) at the same time.

线 = 戋 + 纟 : Mnemonic symbol: barbed wire.

线 = 戋 + 纟 : The silk worm wants to use the floating tank in the anthill's bathroom, but there's already Marie Curie inside—and she secured the tank by setting up barbed wire all around it.

救 = 攵 + 求 : Joan of Arc is using the bathroom in the outhouse just when construction workers are starting to tear the whole place down using sledgehammers without noticing her. Joan of Arc starts to panic and hits a service request bell again and again, hoping that someone will hear it and save her. Unfortunately the sledgehammers are far louder than the bell.

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.
