螺旋槳

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.

桨 = 丬 + 夕 + 木 : A group of bats (夕) throws pieces of wood (丬) at Joan of Arc's (ji) Christmas Tree (木) in the anglepod's living room (ang3), so Joan of Arc shoos them away with a big paddle (桨).
