必不可少組成

必 = 丿 + 心 : Mnemonic symbol: 忽必烈 [Hū​bì​liè​], Kublai Khan. Certainly (必) Kublai Khan (必) has to keep face, but he cannot hold it any longer. In the space station's bathroom (Ø4), He absolutely has to (必) tell Brunhilde (bi) his love for her strong character and offers her his heart (心). Brunhilde is a bit embarrassed because all she has to offer in return is a banana (丿). Kublai Khan feels like his heart has been crossed out (the 丿 stroke is crossing out 心 in 必).

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.

可 = 丁 + 口 : Karl Marx (k) is challenging his abilities (可) in the elevator's living room (e3). He tries to force a nail (丁) into a mandarin (口), just by using his head. On top of that he tries to do so one thousand times, in order to create a bed of nails (mnemonic symbol for 可).

可 = 丁 + 口 : Alternative mnemonic symbol: kebab, from the pronunciation "ke". Karl Marx (k) is preparing a kebab (mnemonic symbol for 可) in the elevator's living room (e3). He also skewers mandarins (口) on the long steel nails (丁) and will only allow (可) his guests to eat the rest of the kebab if they eat their mandarins first.

少 = 丿 + 小 : Mnemonic symbol: 少 looks like a smiley face. There's a food shortage (少) in the aorta, and Sherlock Holmes (sh) and Smiley (少) are looking for food in the living room (ao3). There's only one banana (丿) left. Soon they'll have to eat the many daisies (小) which are growing there.

组 = 且 + 纟 : Zapatista Zebra (zu) and the silk worm (纟) are starting a NGO (组) in the space station (Ø3). The NGO's goal is to distribute as many space friendly shelves (且) as possible. The shelves are radially symmetric and can be rotated so that the centrifugal force keeps the things in the shelf.

成 = 万 + 戈 : Mnemonic symbol: a progress bar stuck at 99%.

成 = 万 + 戈 : Charlie Chaplin is queuing at the engine's kitchen, which is blocked by a neuron until the progress bar above shows 100%. Unfortunately it has been stuck at 99% for two hours now. If it doesn't finish soon, Charlie will get completely mad and destroy the neuron himself with his spear.
