Gibbering Mouther

Amphibious. The mouther can breathe air and water.

Gibbering Mouths. The mouther babbles constantly. A living non-aberration creature that starts its turn within 30 feet and can hear its gibbering makes a DC 10 Intelligence saving throw. On a failure, the creature is confused until the start of its next turn.

Reality Eater. The ground within 15 feet of the mouther is the consistency of sucking mud and is difficult terrain to all creatures except the mouther. Each non-aberrant creature that starts its turn in the area or enters it for the first time on its turn makes a DC 10 Strength saving throw. On a failure, its Speed is reduced to 0 until the start of its next turn.

Multiattack. The mouther makes two bite attacks.

Bite. Melee Weapon Attack: +2 to hit, reach 5 ft., one creature. Hit: 7 (2d6) piercing damage and the target makes a DC 10 Strength saving throw falling prone on a failure. If the target is killed by this attack it is absorbed into the mouther.

Blinding Bile (Recharge 5-6). Ranged Weapon Attack: +2 to hit, range 20/60 ft., one creature. Hit: 3 (1d6) acid damage, and the target is blinded until the end of the mouthers next turn.
