真皮层

真 = 具 + 十 : Mnemonic symbol: a replicator. It generates real and genuine things out of nothing. Looks like a microwave with a cross as antenna. James II of England (zh) broke his replicator (真) in front of the encampment ((e)n1): the cross (十) on the top is broken. Using his toolbox (具), James II of England tries his best to fix it. Fortunately he has a genuine, authorized, real (真) replacement cross.

皮 = ㇖ + 丿 + 丨 + 又 : Mnemonic symbol: a cow's hide.

皮 = ㇖ + 丿 + 丨 + 又 : Just inside the entrance of the space station Pocahontas destroys her cow's hide with a sickle because she decided to go vegan. Instead of leather she'll wear a banana peel as coat, boxing gloves as shoes and a big dinosaur bone as long hat.

皮 = ㇖ + 丿 + 丨 + 又 : New mnemonic symbol, since I also use the cow's hide for 革: leather shoes.

层 = 云 + 尸 : The King of Chu (c) is enjoying a lasagna (千层面) in the engine's kitchen ((e)ng2) when suddenly a ghost (尸) surrounded by a dark cloud (云) appears and starts to haunt him. Terrified, the King of Chu drops the lasagna and runs away. The ghost reached its goal and starts devouring the lasagna himself.
