橡皮筋

橡 = 木 + 象 : Marie Curie (xi) wants to plant some oaks (橡) in the anglepod's bathroom (ang4), so she had the KFNB Elephant (象) transport young oaks to the bathroom. In exchange she provides the train with a lot of Christmas trees (木) to be used as fuel for the steam engine.

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.

筋 = ⺮ + 肋 : Joan of Arc (ji) trained so much that her muscles (筋) burst her harness in front of the encampment ((e)n1). To cover her ribs (肋) she makes a larger armor out of bamboo sticks (⺮).
