余

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).

亼 = 一 + 人 : This one looks like a pointed cap.

Joan of Arc (ji) is going to have her first day of school the next day. During the night she sneaked into the space station's kitchen (Ø2) and found a pointed cap (亼) filled with sweets, which she starts eating immediately.

朩 = 一 + 小 : Let's say this is a sewage pipe which sticks out of the floor. The horizontal line is the floor level, and 小 below it represents the stuff in the earth.
