Grey ooze is indistinguishable from wet stone until it attacks. It will form tentacles that lash out at any who pass. It is corrosive and will eat through chain in 1 round, 2 rounds to eat through plate. It will not damage wood or stone. Magic involving heat or cold does not harm grey ooze but lightning will. Grey ooze also takes full damage from normal weapons, but if the weapon is made of metal it too will begin to dissolve.
As it matures grey ooze gets larger. Specimens over 20 HP can be as large as 36 square-ft. While they cover a huge area they are never more then a few inches deep. At larger sizes they begin to form a kind of consciousness.
