BUT... we might be able to make an exception for shopkeepers that change the way they look over time. I'll probably discuss that with another Admin soon. (Didn't know Metal Mike changed like that... I wonder if I even entered his shop before.)
They're not hard to tell if they're from TTO or TTR. Can confirm the first screenshot is from TTO and the second screenshot is from TTR by looking at the nametags. However, there's already an image of Metal Mike on his page, so it seems rather odd that his shirt was changed to a female shirt.
After going on TTR to check what he looks like, he still has the green shorts and female shirt, but now he has a forest green color for his head. Going to delete the TTO image because it's not really needed.
