甬 = 又 + 用 : Mnemonic symbol: The path screened by walls to both sides could be the grave of Marquis Yi of Zeng. In his grave, a massive set of 64 bianzhong bells was found, of which 45 were 甬钟 bells. Thus, I'm going to represent 甬 by one of these yongzhong bells.

甬 = 又 + 用 : Inside of the engine, Yu the Great wanted to learn how to box. She made the right choice to wear boxing gloves, but as she had no punchbag she used a 甬钟. Like a boss she entered the ring through a path screened by walls on both sides. Unfortunately after her first punch she already had to use the first aid kit, because the bell was way too hard.

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.
