遊刃有餘

游 = 斿 + 氵 : Maud Younger (y) is swimming (游) through a sea of scallops (斿) in the outhouse's kitchen (ou2). Because it is very exhausting, she often has to take a sip from her water bottle (氵).

刃 = 丶 + 刀 : Mnemonic symbol: a (double-edged) two-handed sword.

Robinson Crusoe (r) got a new double-edged sword (刃) and is practising with it in the encampment's bathroom ((e)n4). He starts with cutting his old cleaver (刀), but soon takes the challenge to cut a flying petal leaf (丶) in half.

有 = 𠂇 + 月 : Mnemonic symbol: confetti.

In an act of revolution, with a pair of scissors (𠂇) Maud Younger (y) is cutting a paper moon (月) into tiny pieces in the outhouse's living room (ou3). There is (有) only confetti (有) left over.

余 = 亼 + 朩 : Mnemonic symbol: 余车 means "emperor's carriage", and I'll thus represent 余 with a sedan chair. In the space station's kitchen (Ø2), Yu the Great (yu) finally has the chance to feel like an emperor. In zero gravity she doesn't need anyone to carry the sedan chair (余) she's sitting on. She set up two sewage pipes (朩) right opposite of each other, so as soon as she shoots out of one she enters the other and is redirected to the first one. In this way she can ride her sedan chair in an infinite loop. An emperor always wears a headpiece, so she puts on a pointed cap (亼).
