Ooze

Oozes are formless creatures, somewhat gelatinous in structure. They have very low intelligence and function as a matter of instinct over anything else. They are often considered Mindless and are therefore typically immune to Mind-Affecting abilities. Since they do not have a typical anatomy, they are also immune to Diseases, Poisons & Toxins, Dazed, Stunned, or Stupefied effects, Paralysis, Sickened and Nauseated, and Sleep.
