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.

虫 = 中 + 厶 : Chantal Chicken and a mosquito are taking part in a dart contest just inside the engine's kitchen. The dart board is hanging in the middle of the entrance, and Chantal and the mosquito are standing to the sides. Over each of them a large fake nose is hovering: the loser will be covered in grey goose as punishment.
