Pandaman is usually far more obvious as the mask really looks like a mask. Even in Amazon Lily, the woman's only island, there is Pandawoman and the mask was obvious. So if there is a Pandakid, I think the mask would be obvious but On looking at the page, its at a odd angle, so I can NOT rule it out LOL When Pandaman appeared in the big pile of bodies of Don Kreig's crew, his mask was obvious …but very, very small. so it is possible ... not for Pandaman but maybe Pandakid ;)
True, it is hard to tell (and I'm admittedly pretty bad about spotting Pandaman without someone else pointing him out). Its just the more I look at that panel, the more it really does look like Pandakid (and its mostly the eyes that make me think that).
