国贼

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.

贼 = 戎 + 贝 : Zorro (z) is very afraid that thieves (贼) will steal his crab (贝), so he stores it in a firearm locker (戎) in the Eiffel Tower's kitchen (ei2).
