GIBBERING MOUTHER

Bite. A gibbering mouther can extend up to six pseudopods ending in a mouth to bite a single creature within melee range. Each mouth that does damage will latch on the victim with a grab. If the 'mouther begins a round with 3 or more mouths connected to a victim, it  has a 17% (d%, 01-17) chance pull a Man-sized or smaller creature to the ground as a free action (+10% if the creature has a Dexterity score over 14 or four or more legs). The 'mouther will then engulf the victim. 

Blood Drain. At the end of each round, any creature grabbed by a mouth will suffer 1 point of blood drain (no save).

Camouflage. A gibbering mouther waits for prey with eyes and mouths closed, appearing as a lump of clay or dirt, blending into the surrounding clay, mud, or dirt. Those not surprised will notice a horrific and bloodshot eye staring at them from within the "dirt".

Engulf. A gibbering mouther can engulf any grabbed and prone (or helpless) creature in melee range. It flows over its prey doing 12 points of bite and/or blood drain damage per round (no save). A gibbering mouther can engulf up to two Man-sized (or 4-6 Small) victims. Once engulfed, a victim cannot be freed unless the mouther is killed or it moves off to attack prey out of melee range (which it does if prey ceases to struggle).

Gibber. [sonic, confusion] When a gibbering mouther detect prey nearby, it will begin to gibber, the noise coming from its innumerable mouths. Each round, all creatures in a 60-ft. radius must make a Wisdom save vs. Spell or become confused for 1 round (save negates for that round). If the confusion effect indicates "wander away", the creature gains another +2 Wisdom save (fear) vs. Spell or become panicked for 2 rounds (save negates the confusion effect).

Grab. A creature grabbed by a mouther's mouths can attempt to break free using grapple rules (one break free attempt per mouth).

Movement. A gibbering mouther can drag itself along stone or other surfaces at 30-ft per round. On viscous terrain, such as liquid mud, quicksand, or the result of it's mutate ability, it can move faster, 60-ft per round, and can undulate as if swimming (staying on the surface or diving below as it desires).

Mutate Dirt and Stone. (complex or major, 5 segments) A gibbering mouther can mutate dirt or stone in a 5-ft radius (if using a grid, it's square plus all adjacent squares or simply melee range) turning it into quicksand (if dirt, taking 5 segments) or liquid concrete (if stone, requiring a complex activity) to a depth of 5-ft. The 'mouther can easily move about on the surface. Creatures that sink into the mix are considered to be partially submerged if taller than 5-ft. and fully submerged shorter than this. Those entering the area must make a Dexterity save vs Petrify to avoid sliding fully in (save avoids). Attacking a 'mouther from outside of this area in melee requires an 8-ft or longer weapon. Once the mouther has vacated the area of effect, the affected area begins to transform back into its regular form after 5 rounds, taking another 5 rounds to become solid again.

Spit. (minor) Once per round, a 'mouther can expectorate a globule from one of its mouths at any hard surface in 30-ft. When striking the surface, the globule explodes in a flash, causing creatures within 30-ft. (unless facing directly away) to make a save vs Petrify or be blinded for 1 round (save avoids).

Disgusting, loathsome, and hungry—these are the only words that properly describe the gibbering mouther. A foul beast that lurks in underground caves, sewers, and nightmares, mouthers have no societal, ecological or religious significance other than their ability to drive those that listen to them mad. 

Description. This horrid mass of eyes, mouths, and formless flesh stares in all directions, its countless maws yammering ceaselessly.
