I think I've seen one of the shadowed pokemon before at a few shops in Hong Kong. There were glass cases with little plastic pokemon inside. Surrounded by other pokemon , was a pokemon I've never seen before. Its face looked like Chimecho , but the shape of the head and body was different than Chimecho. It looked like a grass type. So I think the shadowed pokemon in the middle is what I saw. I'm not completely sure about this though. I've only seen it in at least two shops already.
