桶

桶 = 木 + 甬 : engine's fire alarm went off and the yongzhong bells (甬) are ringing very loudly. Inside of the engine ((e)ng3) a Christmas tree (木) is on fire, and Tommy Turtle (tu) is helping to quench the fire by spilling water on it using a wooden bucket (桶).

木 = 八 + 十 : Mnemonic symbol: a Christmas tree. Malte Monkey is putting up a Christmas tree (木) in the bathroom of the space station (Ø4). He's using a cross (十) as a base to put the tree on, and decorates the tree with eight-balls (八).

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.
