This creature looks like a man-sized sandy brown starfish with five long tentacles ringing a central maw lined with sharpened teeth and fangs.

A dust digger can glide through sand, loose soil, or other loosely packed earth as easily as a fish swims through water. Its burrowing leaves behind no tunnel or hole, nor does it create any ripple or signs of its presence. A move earth spell cast on an area containing a burrowing dust digger flings the creature back 30 feet, stunning it for 1 round unless it succeeds on a Fortitude save.
A buried dust digger can deflate its body as a free action, causing the sand above it to slide toward its maw. A creature standing on a space occupied by a buried dust digger when it deflates is immediately subjected to the dust digger’s tentacle attacks.
