万 = 丆 + ㇆ : As mnemonic symbol I choose a neuron, since each neuron is said to connect to 10000 others.

万 = 丆 + ㇆ : Willy Walrus needs to dig up the floor in the anthill's bathroom, but he is tired of doing so manually with a plough. To make his life easier, he sets up a wind wheel for electricity, connects a neuron to the wind wheel and the plough to transmit the electricity and uses his new DIY electric plough to dig much faster.

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.

博 = 十 + 尃 : Just after he got a PhD (博), Beelzebub (b) opened a museum (博) in the observatory's kitchen (o2). He put a big notice on the bulletin board (尃) to announce (尃) the grand opening. His museum is rather special in that it showcases Jesus's cross (十).

览 = 刂 + 大 + 见 : There's an exhibition (览) of kitchen knives (刂) in the anthill (an3), and Sir Lancelot (l) cannot resist but to steal one of the knifes. Unfortunately the robot (大) used his hidden surveillance camera (见) to record the deed.

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.
