Blubber Being

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

Fluid Form. The being can use an action to melt into a formless blob. While in its form, the being's speed is decreased by 10 feet., and its attack range is increased by 5 ft, and the attack name is changed to Pesudopod. While the being is in dim light or darker, it takes a successful DC 15 Wisdom (Perception) check to spot a melted being that has neither moved nor attacked.

Death Burst. When the being dies, it explodes in a splatter of blubber and acidic slime. Each creature within 20 feet of it must make a DC 9 Dexterity saving throw, taking 14 (3d8) acid damage on a failed save, or half as much on a successful one. Objects that aren't metal thicker than 1 inch that arent being worn or carried in that area dissolve over 1d4 turns. A creature can take an action to wipe off the slime, ending the effect. If the being died to cold damage, this trait does not occur.

Action Melee Attack. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) bludgeoning damage plus 9 (2d8) acid damage.

Absorb. Whenever the being is hit with a weapon that deals bludgeoning damage, it is absorbed by the it. The weapon can only be retrieved by a wish spell. One of the being's hands, or one of its pesudopods, turns into a copy of the weapon (Both hands, or pesudopods, turn into weapons if it was hit with a two weapon attack). It then attacks the creature whose weapon it absorbed. Ignoring resitances and immuninties, as well as heavy and two-handed weapon properties, the being deals the amount of bludgeoning damage it was originally dealt plus 9 (2d8) acid damage.
