螺旋曲面

螺 = 累 + 虫 : Lenny Lemur (lu) is trying to catch a mosquito (虫) in the observatory's kitchen (o2). To this end he attached a conch (螺) to the end of a rope (累) and throws the conch at the mosquito, hoping to catch it inside. After a miss he can just retract the conch with the rope.

旋 = 方 + 𠂉 + 正 : Mnemonic symbol: a whirlwind.

Xu Xian (xu) is delivering packets in the anthill's kitchen (an2). First he has to disable the alarm, so he uses the key (𠂉) to open a square (方) and pushes the button. Next he whirls around the room delivering his packets so quickly that he creates a whirlwind (旋), which is so fierce that the stick figure (正) gets blown all around the room.

曲 = 囗 + 卄 : Mnemonic symbol: a harp. Cupid (qu) is playing a harp (曲) in the space station's living room (Ø3). He's sitting on a big enclosure (囗), playing the harp (曲) and wielding a double axe (卄) at the same time.

面 = 丆 + 囬 : Mnemonic symbol: a spray flask with one of these liquids which make a surface super slippery.

In the anthill's bathroom (an4), Marilyn Monroe (mi) wants to set up a wind wheel (丆) on top of a closet (囬). Just as she tries to fix it she slips and falls down, the wind wheel crashing on the floor. She didn't notice that somebody used a can of non-stick coating (面) on the closet's surfaces (面).
