They're identical, with some little bits and pieces that probably changed over time and in the quality of the pictures.
Doesn't mean the first image isn't a goblin though! Maybe a complete replica was placed in to debunk a real incident. Probably not... but possible!
I agree. And the Cs are so cryptic about it.
The creature looks identical, but the crevasse seems to be different. Upon immediate inspection, it looks like it must be the same, just different lighting, so probably the only way to tell would be for somebody with photo manipulation skills to superimpose one on the other to see if the match is as it appears to be.
Of course, if you think about it, if anybody ever DID get a photo of such a thing and it was real, there would be a lot of effort to debunk it, even to the extent of replicating it and making it look silly. Look what they did with the alien autopsy... and the guy who now says he was behind it - who didn't show up for years - has a sudden windfall of funding and so on.
That is a favorite trick of disinfo, after all.
