An Awakened Mimic takes a hybrid form similar to whatever they were recently mimicking and therefore have proportions that may be different than humans. Though in general they are shorter on average than humans and relatively squat. Your size is Small or Medium.

You can use an action to polymorph yourself into an object or back into your true form.  Your statistics are the same in each form, though your size may be one size smaller.  In any polymorphed form your mass is preserved, so objects smaller than your base form are dense than expected and vice versa. Polymorphed forms cannot Objects you are wearing or carrying merge into your transformed form.  While transformed, you can speak, move at half your speed, and make unarmed strikes with your pseudopods.  You cannot cast spells with somatic or material components, or use objects while transformed, and you revert to your true form when you drop to 0 hitpoints or die.  Finally, while motionless and silent, you are indistinguishable from the mimicked object, except that your form remains slightly sticky to the touch. 

Your base walking speed is 30 feet.

You have proficiency in the Deception and Stealth skills.

Because of your biology, your arms can be used as natural weapons, which you can use to make unarmed strikes. If you hit with them, you deal bludgeoning damage equal to 1d4 + your Strength modifier, instead of the bludgeoning damage normal for an unarmed strike.

You cannot naturally speak, read, and write any language other than common.
