垂 = 壬 + 工 + 工 : The cat o' nine tails (壬) has been chasing Chantal Chicken (chu) all around the Eiffel Tower. In the kitchen (ei2) there is a weeping willow (垂, 垂柳) on which Chantal Chicken sits.

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.
