ATAAAAAAAAAAAAAAAAAAACK!!!!!!!!
*ahem*
Sorry, couldn't resist.

Anyway, I recently received my long awaited MST3K: Season 11 Blu-ray box set in the mail, and spent an afternoon watching all of the exclusive content. It was a treasure trove of information, and featured a lot of images from the production spread out over the documentary and two image galleries.
One of those images was a nice close up of everyone's favorite Jonah-eating, metal ceiling snake, the mysterious Reptilicus Metalicus.
The image reveals the prop to be a hand puppet, and one that appears to have its basis in found objects. Whether or not these are 3D printed copies of original objects is unknown, but I can tell you right now - and I know a thing or two about a thing or two after so much Waverly research - that I know a sandcastle mold when I see it.

That said, now that I know what Reptilicus Metalicus' nose is, the Bot Building Bug has bitten me again, and I now have to know what the rest of him is. I'd love one of these guys hanging from MY ceiling, albeit on a smaller, less dangerous scale, of course.

Once again, my friends... THE HUNT IS AFOOT!
