I see 4 screws down the middle, and 2 on the front both sides. I was trying to avoid taking apart the wheels assemble which appears to be held together by the 4 screws. I dcc Thomas without any problems. I am sure DD would be straight-forward too if I could properly remove the hood. Any suggestions?

I want to buy a Devious Diesel, but I am very unhappy with the friendly smiley face. I don't necessary am looking for a mean evil look, but at least a smirk. Is there a change coming in the product or is there a way to buy a replacement face?
Is there anything I can do?
