勿忘國恥

勿 = 丿 + 勹 : Mnemonic symbol: bat wings.

勿 = 丿 + 勹 : The elephant wants to eat a banana in the space station's bathroom, but Willy Walrus suddenly flies by (using bat wings), snatches the banana away and shouts "no!"

忘 = 亡 + 心 : Willy Walrus (w) will never forget (忘) his love who is buried in the anglepod's bathroom (ang4). There is not a single day when Willy forgets (忘) to bring his heart (心) and leave it right next to his love's tombstone (亡).

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.

耻 = 止 + 耳 : Charlie Chaplin (ch) is disgraced (耻) by hearing what is happening on earth, so in the space station (Ø3) he decides to put a barrier (止) into each of his ears (耳) so that he won't have to listen anymore.
