I agree that the skeleton is a very different quality than what you get with the other figures, but I just put that down to a last minute freebie that was added in for the backers. It was free, and I only had the cash to pay for the one figure, so I'm not complaining about it. My pinky has a problem with being knock-kneed, but he feels mostly solid. He even took some unintentional bending at base of his neck without breaking. So he feels cheap, but he's surprisingly sturdy.
Of course if you aren't happy with them then I'd be more than happy to take that coral snek and skeleton off your hands whenever I have money again!
