Mud Elemental, Elder

This animate pile of mud seems barely able to maintain the semblance of a humanoid form made of dripping sludge.

Earth Glide (Ex)

A burrowing mud elemental can pass through dirt, gravel, or other loose or porous solid matter as easily as a fish swims through water. It cannot use this ability to pass through a solid barrier such as a stone or brick wall. Its burrowing leaves behind no tunnel or hole, nor does it create any ripple or other sign of its presence. A move earth spell cast on an area containing a burrowing mud elemental flings the elemental back 30 feet, stunning the creature for 1 round unless it succeeds on a DC 15 Fortitude save.

Entrap (Ex)

The mud from an elemental’s entrap ability can be washed away in 1d3 rounds of immersion in water.
