萬般無奈

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.

般 = 殳 + 舟 : Mnemonic symbol from 般雀·比拉多, Pontius Pilatus

In front of the anthill, Beelzebub is waiting for Pontius Pilatus to take him to hell with his yellow submarine. Pontius tries to defend himself with a halberd, but Beelzebub only laughs at him.

无 = 一 + 𠂇 + 乚 : Mnemonic symbol: the philosopher Diogenes, who has nothing and wants nothing.

无 = 一 + 𠂇 + 乚 : Just inside the space station's entrance, Diogenes is annoyed by Willy Walrus, who's playing his flute. Diogenes just wants a peaceful time without being disturbed, so he cuts the flute into pieces with a pair of scissors, and threatens to beat Willy Walrus with a shovel should he annoy Diogenes again.

Mnemonic symbol: 無爲, wu2 wei2, the state of non-doing after having attained complete harmony with the Tao.

Willy Walrus (w) has attained Wu Wei (無) just inside the space station's entrance (Ø2), while from the outside it may seem like he is napping.

奈 = 大 + 示 : Napoleon (n) wants to put his guideon (示) on the peak of Mount Sinai (奈) in the airplane's bathroom (ai4), but the robot (大) normally responsible for carrying his guideon is broken. Without any better option (奈) Napoleon will have to carry up the guideon himself.
