So something like this?
Earth Glide (Ex): A shadowcrawler can glide through stone, dirt, or almost any other sort of earth except metal as easily as a fish swims through water. Its burrowing leaves behind no tunnel or hole, nor does it create any ripple or other signs of its presence. A shadowcrawler can also carry a grappled Medium or smaller creature through earth.
A phase door or move earth spell cast on an area containing a burrowing shadowcrawler kills the shadowcrawler and any creature it carries instantly if they fails a Fortitude save (DC determined as usual by spell level and caster ability modifier).
