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

Pseudopod. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 11 (2d8 + 2) bludgeoning damage.

Mind-eat. The viscomorph moves into a creature's space and surrounds its head. The creature must succeed a DC 13 Strength save or become grappled and begin to suffocate. At the beginning of the viscomorph's turn the target 4d8 acid damage. 

Read Thoughts. The viscomorph magically reads the surface thoughts and gets an idea of their memories of what people they know look like of one creature within 100 feet of it. The effect can penetrate barriers, but 10 feet of wood or dirt, 5 feet of stone, 5 inches of metal, or a thin sheet of lead blocks it. While the target is in range, the viscomorph can continue reading its thoughts, as long as the Viscomorph concentration isn't broken (as if concentrating on a spell). While reading the target's mind, the viscomorph has advantage on Wisdom (Insight) and Charisma (Deception, Intimidation, and Persuasion) checks against the target.

Form shift. The Viscomorph can change shape and color to appear as any creature or object it has seen before. Its stats remain the same in any form. While in this form a DC 18 perception check can identify it to be a Viscomorph.

Split.  After a viscomorph kills a creature using its mind-eat ability, it splits into two new viscomorphs, one with the memories, personality and alignment of the creature that was consumed. Each new viscomorph has hit points equal to half the original viscomorph's, rounded down. The new viscomorphs are small.
