國寶

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.

宝 = 宀 + 玉 : Beelzebub is busy drawing fake jewels and jade bracelets from a graduation cap in the aorta. He uses his magic graduation cap to change coal into precious treasure like jewels and jade bracelets to deceive and seduce humanity.
