Helga Horse (hu) tries on her new monk's cowl (礻) in the observatory's bathroom (o4), but she soon realizes a disaster (祸): in her monk's cowl, her breasts look lopsided (呙).

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.
