敵國

敌 = 攵 + 舌 : Dorothy Gale (di) is fighting her enemy (敌), the Wicked Witch of the West, by attacking her with a sledgehammer (攵) while threatening her with her tongue (舌) stuck out just inside the space station's entrance (Ø2).

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.
