In the Dungeons & Dragons role-playing game, Ooze is a type of creature, or "creature type". This category includes such monsters as slimes, jellies, deadly puddings, and similar mindless, amorphous blobs.
Many oozes dwell underground, and most secrete an acid from their skin that dissolves flesh and other materials rapidly.
Oozes are essentially blind, but more than make up for that with an ability called "blindsight", which allows them to discern nearby objects and creatures without needing to see them.
The following are examples of oozes listed in the Monster Manual, one of the three core rule-books for Dungeons & Dragons. Black pudding Gelatinous cube Gray ooze The gray ooze resembles a thick, viscous puddle of gray sludge, roughly 6 to 8 inches thick and up to 14 feet across, and often closely resembles wet stone or an amorphous rock formation. Like most oozes, they are underground dwelling, mindless scavengers who drag themselves around caves and sewers and absorb and digest whatever they find. Unlike some other oozes, it cannot move on ceilings or walls, and hence is left to slide its way along floors. The gray ooze attacks by striking like a snake until prey is either dead or unconscious, and it then moves on top of them to digest them from within. It is immune to cold and fire. The gray ooze's acidic secretions corrode metal at an alarming rate, and in addition to giving the creature a method of destroying opponent's weapons and armor, blacksmiths also sometimes use jarred gray oozes to meld ore into the right shape. Gray oozes reproduce by breaking small driplets off of themselves after a meal, which later grow into gray oozes themselves. Ochre jelly The ochre jelly resembles a giant amoeba, consisting of a thick, porous, golden sludge stiffly built up into the amoeba shape. It lurks in dungeons, slowly sludging its way along floors, walls and ceilings alike, under doors and through cracks, looking for victims. When it finds them, it extends, latches onto them, and then proceeds to engulf and constrict them. The ochre jelly reproduces asexually, and can sometimes be found with several of its divided offspring.
