之 = 丶 + Z : Mnemonic symbol: Sooo sleepy... "zZz" (the character looks like a "Z"). James II of England (zh) fell asleep in front of the space station (Ø1). He sleeps on a big petal leaf (丶), making loud "zZz" (之) sounds.

亦 = 亠 + 小 + 丿 : Mnemonic symbol: An also-ran, a very exhausted runner.

亦 = 亠 + 小 + 丿 : The also-ran arrives very late at the space station's bathroom. In fact she arrives so late that Maud Younger who was waiting for her with a daisy fell asleep on a big cozy beret. The also-ran came so late because she ate many bananas on the way.

然 = 灬 + 肰 : Robinson Crusoe is grilling some dog meat on his BBQ in the anthill's kitchen, but it's hard to do it correctly because of all the animal rights activists. They think it's not right to grill dog meat.
