叶城

叶 = 十 + 口 : Maud Younger (y) practised a trick shot all day in the elevator's bathroom (e4). She's now able to throw a leaf (叶) high in the air, then quickly throw a mandarin (口) and beat the mandarin with a cross (十) like a baseball with a bat so that the mandarin rips a hole right into the leaf.

叶 = 十 + 口 : You could see the cross 十 as the leaves 叶 of the mandarin 口.

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.
