156 OOZE ROOM. The door to this room is locked. The gray key from Room 160 will open it.
An unusually large gray ooze is in the room. A lever is on the wall near the door.
Gray Ooze (AC 8; MV 1”; HD 6+6; hp 35; #AT 1; D 2-16; SA Corrosive properties; SD Immune to spells, heat, cold, psionics; XP 1055)
There is actually a wall of force located five feet from the door and dividing the room into east and west halves. The lever turns it on and off. The apes usually turn it off, throw food at the ooze and turn it on again quickly.
The ooze is psionically aware and can perform a psychic crush if stimulated psionically.
