丰城

丰 = 三 + 丨 : Mnemonic symbol: a luxurious golden cage.

Frankenstein's Monster (f) has been locked in a golden cage (mnemonic symbol for 丰) in front of the engine ((e)ng1). The golden cage is suspended from a coordinate system (三). In the cage there are still the dinosaur bones (丨) from the previous prisoners.

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.
