象虫

象 = ⺈ + 口 + 豕 : Mnemonic symbol: I already used an ordinary elephant for 勹, which is fine, because 勹 appears many times and 象 only a few times. Thus to represent 象 I'll use a locomotive from 1844's Austria, which was called "KFNB Elephant".

象 = ⺈ + 口 + 豕 : Marie Curie sees the crane and the swine fight about a single mandarin in the anglepod's bathroom. To smooth down the differences, with a locomotive she drives a whole container of mandarins in the bathroom.

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.
