八
:
Mnemonic symbol from the shape of the character: a sea star. Xi shi (xi) and a sea star (⺍) have a strong desire (兴) to smoke catnip (⺍) through a flute (一), so they hide in the engine's bathroom ((e)ng4) to crush the catnip with an eight-ball (八) and smoke it. Shortly afterwards they relax and loose all their excitement (兴) and interest in anything (兴).
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.
