觸線

触 = 虫 + 角 : Chantal Chicken (chu) found a way to listen to a mosquito (虫) in the space station's bathroom (Ø4): The mosquito is speaking into the small hole of a horn (角), and Chantal holds her ear to the wide end of the horn. In this way she can listen to the very touching (触) stories of the mosquito. After the mosquito finished Chantal wants to touch it (触) and pat it on the shoulder, but she accidentally smashes the mosquito.

线 = 戋 + 纟 : Mnemonic symbol: barbed wire.

线 = 戋 + 纟 : The silk worm wants to use the floating tank in the anthill's bathroom, but there's already Marie Curie inside—and she secured the tank by setting up barbed wire all around it.
