Amorphous.

The ooze can move through a space as narrow as 1 inch wide without squeezing.

Spider Climb.

The ooze can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.

Actions

Multiattack.

The ooze makes two Pseudopod attacks. The ooze can replace one Pseudopod attack with its Slime Breath, if available.

Pseudopod.

Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 9 (1d10 + 4) bludgeoning damage plus 14 (4d6) acid damage. If the target is a Large or smaller creature, it is grappled (escape DC 15). Until this grapple ends, the target takes 7 (2d6) acid damage at the start of each of its turns.

Slime Breath (Recharge 6).

The ooze expels a spray of its gelatinous mass in a 30-foot cone. Each creature in that area must make a DC 14 Dexterity saving throw. On a failed save, the creature takes 22 (4d10) acid damage and is pulled up to 30 feet straight toward the ooze. On a successful save, the creature takes half as much damage and isn't pulled.
