疲困

疲 = 疒 + 皮 : Pocahontas (pi) finally arrived at the space station. Just inside the entrance (Ø2) she feels very weary (疲) and curls into a cow's hide (皮). She feels very sick and develops a colorful rash (疒). She doesn't know that it's not because of the long journey, but because of her allergy against the hide.

困 = 囗 + 木 : New mnemonic symbol to avoid confusion with 夗: sleeping pills.

Karl Koala (ku) prepared a nest made out of Christmas trees (木) stuffed into a plastic enclosure (囗) in the encampment's bathroom ((e)n4). To make sure that he sleeps (困) really well he pops sleeping pills (困) before laying down in his nest.
