Pinyin "luo2"

罗 = 夕 + 罒 : Lenny Lemur wanted to catch a few bats with a net hang high across the observatory's kitchen. Instead, two bats catch him in a roll of gauze in a fly-by manoeuvre.

逻 = 罗 + 辶 : Lenny Lemur (lu) is patrolling the observatory's kitchen (o2) in his patrol boat (逻). He is patrolling three gates: behind two of the gates there is one pile of gauze (罗) respectively, but behind the last door there is a pair of beautiful gladiator sandals (辶). He will ask any visitor to choose one of the gates, then open another one and show the gauze behind it. Any visitor who doesn't get the logic (逻) why it is better to choose the remaining gate then is not allowed to enter the castle.

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.
