国宴

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.

宴 = 妟 + 宀 : The sun (妟) graduated and invites her good friends Bessie Coleman (妟) and Maud Younger (y) into the anthill's bathroom (an4) to a brunch during a bright and clear sunrise (妟). She's wearing her graduation cap (宀) all the time and doesn't take it off even once.
