聖城

圣 = 又 + 土 : Mnemonic symbol: Father Christmas, 圣诞老人.

Sherlock Holmes is about to lose against Santa Claus in a boxing match in the engine's bathroom when he uses a dirty trick: lying on the floor he grabs some dirt and throws it into Santa Claus's face, thereby blinding him. Sherlock uses the opportunity to land a critical blow onto Santa Claus's big belly, but Santa doesn't even notice.

城 = 土 + 成 : Again Charlie Chaplin is unable to exit engine. There is a wall of dirt blocking the entrance, and a progress bar showing that it will be removed soon, but the bar seems to be stuck.
