    In the book (and in the first movie) they specifically talk about “drum sand”, in the book it’s explained that it is a specific condition of the sand bed due to wind or something. Maybe Neil missed that?

    I get his point about worm movement, though.

      I assume the worms move with something akin to jet propulsion. They suck sand in the front continuously and it travels all the way through them and out the back.
