國貨

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.

货 = 化 + 贝 : Helga Horse (hu) is using a transformer (化) to roast crabs (贝) in the observatory's bathroom (o4). Later she wants to sell the roasted crabs (货) as commodity (货) for money (货).
