The only claim is for the ornamental design (which I'd have thought
wasn't even patentable). There's no indication that they even think it
could fly.

"Ornamental Design" is a figleaf for patenting a particular shape or
configuration without having to give away any of the technical details.
And yes, they are patentable, although very specific.
