國畫

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.

画 = 一 + 田 + 凵 : Helga Horse (hu) decided to make the ashram's bathroom (a4) more beautiful, so she paints (画) her favourite field (田) on the wall using a flute (一). She doesn't watch out for the receptacles (凵) though, and gets shocked as her flute gets stuck in one of them.
