Blue (Awakened Blue Slime Mold)

Amorphous. Blue can move through a space as narrow as 1 inch without expending extra movement to do so.

Corrosive Form. Nonmagical ammunition is destroyed immediately after hitting Blue and dealing any damage. Any nonmagical weapon takes a cumulative −1 penalty to attack rolls immediately after dealing damage to Blue and coming into contact with it. The weapon is destroyed if the penalty reaches −5. The penalty can be removed by casting the Mending spell on the weapon. As Blue acts almost as organic nanobots.

Blue can eat through 2-inch-thick, nonmagical metal or wood in 1 round.

Pseudopod. Melee Attack Roll: +3, reach 5 ft. Hit: 10 (2d8 + 2) Poison damage. Nonmagical armor worn by the target takes a −1 penalty to the AC it offers. The armor is destroyed if the penalty reduces its AC to 10. The penalty can be removed by casting the Mending spell on the armor. 

 Morph. Blue can expand itself and change its shape to copy the form of another creature. Although they keep their blue color. The smarter an Awakened Blue Slime Mold the better the disguise.

Envelop. Blue may choose to launch themselves at a creature to envelop them, coating the creature with themselves. If Blue likes this creature they wrap protectively around them, granting the creature a +1 bonus to AC and resistance to nonmagical piercing, slashing, and bludgeoning damage. However if they do not like you Blue will begin to release toxic poison as it begins to feed on a creature and its equipment. However applying fire will force Blue to retreat, dealing double damage to Blue and the creature they are enveloping.

Mesmerize. Blue has full control over their bioluminescence and can create mesmerizing patterns that look spectacular and enthrall those who bear witness. Blue can do so as a reaction imposing disadvantage on an attack roll. Although this requires more energy and can only be done 3 times per long rest. Although by consuming matter Blue can regenerate uses.
