尾張國

尾 = 尸 + 毛 : Willy Walrus (w) knows that there is a ghost (尸) in the Eiffel Tower (ei3), but he cannot see it, so he set up a trap: he put a lot of sticky hair (毛) everywhere, and eventually the hair stuck to the ghost's tail (尾). Now that Willy Walrus can see where the ghost is he is able to drive it out.

张 = 弓 + 长 : Mnemonic symbol: a spreadsheet. James II of England (zh) practices his archery skills in front of the anglepod (ang1). Riding on a longboard (长) he shoots arrows using his composite bow (弓) trying to hit a spreadsheet (张).

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.
