万不得已

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.

不 = 丆 + 卜 : Bruno Bear (bu) is setting up a wind wheel (丆) with a voodoo staff (卜) in the space station's bathroom (Ø4). He also puts a "forbidden" sign (mnemonic symbol for 不) on it, to make clear that it may not (不) be stopped.

得 = 㝵 + 彳 : Don Quixote found a magic lamp and rubs it inside the elevator's kitchen. A genie appears and grants Don Quixote his wish for black sneakers. Unfortunately they are second hand and so smelly that Don Quixote instantly catches a disease.

得 = 㝵 + 彳 : Because Don Quixote is so disappointed by the black sneakers he got from the genie from the magic lamp, he kicks both very mad from the rooftop of the elevator.

得 = 㝵 + 彳 : Because Don Quixote kicked the genie's lamp from the rooftop of the Erechtheion as far as to inside of the Eiffel Tower, the genie demands Don Quixote to apologize. Inside of the Eiffel Tower, Don Quixote kowtows to the genie, who takes back the black sneakers he gave to Don Quixote earlier.

已 = ㇖ + 一 + 乚 : Kinda looks like a dredger. Maud Younger wants to dig a tunnel from the space station to earth, so she already used a dredger to dig up the walls just inside the space station. Unfortunately there are a lot of flutes built into the wall, and the dredger is of no use here, so she had to stop. Instead she then has to use a shovel and a sickle to scratch the flutes free and lever them out afterwards.
