英 = 艹 + 央 : Mnemonic symbol: a hero. An evil villain has been terrorizing the UK (英), so Maud Younger (y) and the hero (英) want to stop him. They know that he will visit engine later that day, so in front of the engine ((e)ng1) they prepare artificial lawn (艹) by adding a CPU (央) to each sheet. This way, each sheet acts as intelligent automated trap which will grab the villain once he steps on the sheet.

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.

石 = 丆 + 口 : Sherlock Holmes finds the space station's entrance blocked by a big rock. He uses a wind wheel and a mandarin to build a lever, with which he is able to move the rock.
