中國鳥類學會

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.

Nefertiti tries to fend off a turkey in the aorta.

类 = 大 + 米 : Lancelot (l) wants to save mankind (类), so he plans to breed the perfect rice plant. To find the perfect seed he programmed a robot (大) to classify (类) every corn of a sack of rice (米) in the Eiffel Tower's bathroom (ei4) so he can choose the best one.

学 = 小 + 冖 + 子 : Xu Xian wants to study scienceology and learn more about daisies. Just inside the elevator's kitchen, he put some daisies into a prize cup and covered them with a cooking top. He wants to study the growth rate of the daisies depending on the pH of the water in the prize cup.

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.
