Skills:

• Spider Climb. The mimic can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.

• False Appearance (Object Form Only). While the mimic remains motionless, it is indistinguishable from an ordinary object.

• Hungry Pocket. The mimic can hold the equivalent of a jewelry box worth of items of any weight. If the mimic is not fed 3 small items a day (ex: coin, rock, charm) it will feed itself from its environment, prioritizing shiny metal items. When properly fed, it will gladly hold items for its owner and can be taught a command word to use the Bite attack on any who try to loot it.

Damage Immunities: Acid

Condition Immunities: Prone

• Darkvision (60 ft.)

• Passive Perception: 11

Languages: Common, Undercommon

• Command: The baby mimic is capable of learning one Command, a one-word order to complete a simple action (ex: Hide). The command is taught over 1d4 hours and is consistent. To train a new command, the old one must be unlearned over a short rest before the new one is taught. Additional commands may be learned later as the mimic ages. The DM may need to approve the Command.

Actions

• Bite. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 1 piercing damage plus 2 (1d4) acid damage.

• Shape-Shift. The mimic polymorphs into an object or back into its true, amorphous form. Its statistics are the same in each form. Any equipment it is wearing or carrying isn't transformed. It reverts to its true form if it dies.

• Adhesion. The mimic secretes a sticky saliva and is developing sticky pseudopods. Using its tongue and/or pseudopods, the mimic can cause small objects to adhere to it or hold firmly to things.

• Gummy Bite. The mimic's teeth are still growing and rather than damage it can latch onto someone to hold on tightly. For 1d6 rounds, the mimic latches onto a creature's hand, causing them disadvantage on attacks. The creature can make a contested Strength check to pry the mimic off. While latched like this, the mimic cannot use its Bite attack.

• Plaintative Wail. The mimic can solicit the Help action from any bonded creature or its siblings by emitting a cry. The cry can be heard up to 40 feet away and cannot be used if the mimic is using its tongue or bite actions (gummy or not).
