Yep, I'm totally aware that 5e stats for these monsters are already available in a number of books and sites. However, for my games (these guys appear on a random encounter table for one of my campaigns) they didn't come close enough to the original, 1st Edition AD&D version - the one with the shiny shell that could make your spell casters mess up big time, and which got upset in bright light - so I statted up my own version. Being nice, and wanting to share, I thought I would stick it on here, so you have, if nothing else, another variant on the ones already out there.
