國樂

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.

乐 = ⺁ + 朩 : Mnemonic symbol: a cheerleader

乐 = ⺁ + 朩 : In the elevator's bathroom, the cheerleader is beating Lancelot on the head with a banana tree just when Lancelot isn't watching, and laughing at him cheerfully. The cheerleader sneaked up on Lancelot by popping out of a sewage pipe.
