護國軍

护 = 户 + 扌 : Helga Horse (hu) feels that she has to protect (护) the inhabitants of the space station. In the bathroom (Ø4) she equips herself with a wooden swinging door (户) as a shield and a toy claw (扌) as a weapon.

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.

军 = 冖 + 车 : As a component in other characters: a general.

Zeus is driving a car in front of the restaurant. It's a cabriolet, so he uses a cooking top to protect himself from the weather. With the cooking top on his head, he looks kinda like a weird general.
