An ooze that lives in the Underdark, the slithering tracker is a glistening creature of transparent ooze, typically small size. When still, it looks like a wet patch of stone or a patch of condensation on a wall. Comparatively slow moving, the slithering tracker relies on its transparency and knack for ambushing to surprise prey.
The unique nature of slithering trackers gives them the distinct advantage of being able to slip through cracks and holes as small as a rat hole. They move completely silently across all surfaces, simply oozing slowly over all bumps and turns. They prefer to attack sleeping, solitary, or unconscious creatures, as their main weakness lies in the extended duration of their attack form. They secrete a paralyzing substance that immobilizes the victim.
