亡国

亡 = 乚 + 亠 : Willy Walrus (w) just finished digging a grave (亡) for his dead relatives who were killed in the Arctic in the anglepod's kitchen (ang2). Exhausted, he sticks the shovel (乚) in the earth and puts his beret (亠) on it. Finally, he sets up the tombstone (mnemonic symbol for 亡).

亾 = 乚 + 人 : My mnemonic for 亡 is a tombstone, so this ancient variant gets to be a sarcophagus.

Willy Walrus (w) has to bury the Neanderthal man (人) in the anglepod's kitchen (ang2). The Neanderthal man (人) is lying in a half open sarcophagus (亾) next to Willy, and Willy uses a shovel (乚) to dig the grave.

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.
