中 = 丨 + 口 : Mnemonic symbol: a dart board, because you always try to hit the center.

Julian Giant Squid (zhu-) is throwing dinosaur bones (丨) as darts on a dart board in front of the engine ((e)ng1). To make it a bit more difficult he's throwing mandarins (口) into the air as well and skewers them up right in the center (中 is a mandarin skewered on a dinosaur bone) in mid flight with the dinosaur bones. He's still able to consistently hit the center (中) of the dart board.

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.

证 = 正 + 讠 : James II of England (zh) is not allowed to stay any longer in the engine, so in the bathroom ((e)ng4) he forges a visa (证) so he can stay. On an advertising column (讠) he scribbles his fake visa, but (like me) he sucks at drawing, so he is only able to draw a stick figure (正) where his photo should go.

监 = 刂 + 大 + 皿 : Joan of Arc (ji) has been caught by the English and in her prison (监), a cage (监) in front of the anthill (an1), She awaits her trial. She has not given up, though: as a robot hands her a bowl of rice (皿), She quickly pulls out a kitchen knife (刂) and stabs the robot's (大) arm. The robot doesn't even notice though.

会 = 云 + 人 : Helga horse is almost fainting when she enters the Eiffel Tower's bathroom. Neanderthal man is giving off an extraordinarily smelly cloud. She didn't even think that this was possible at all.
