User blog comment:Thechosenone124/Poll: Is this Delver Missing Legs?/@comment-26983242-20181021094413

And why is it you want to know? If it is to include the info on an article, I'd have to say that it'd be too anecdotal of a piece of evidence to support anything—there should be little speculation and more clear-cut, no-doubt-about-it facts. I know how you love this kind of stuff, so please, keep that to your Reddit posts or internal wiki pages, where it's clearly marked as speculation—you may go all out there.

As to if they are missing legs, it sure seems so. But it also might be an error in drawing—I'd not be confident unless there were more panels.
