When the protean abomination kills a creature that is neither a construct nor undead, it absorbs the corpse into its body and regains 20 hit points.
The protean abomination can move through a space as narrow as 1 inch wide without squeezing.
The protean abomination can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.
The protean abomination makes two slam attacks. If both attacks hit a Large or smaller target, the target is grappled (escape DC 15), and the protean abomination uses Engulf on it.
Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 19 (3d8 + 5) bludgeoning damage.
The protean abomination engulfs a Large or smaller creature grappled by it. Until the grapple ends the target is blinded, restrained, and unable to breathe, and it must succeed on a DC 15 Constitution saving throw at the start of each of the abomination's turns or take 19 (3d8 + 5) bludgeoning damage. If the abomination moves, the engulfed target moves with it. The abomination can have only one creature engulfed at a time.
