返国

返 = 反 + 辶 : The protester (反) just entered the anthill (an3) wearing socks and gladiator sandals (辶). Frankenstein's Monster (f) protests loudly and tells the protester to go back (返) where he came from to either wear sandals and no socks, or socks and proper shoes.

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.
