A weird tall meaty skinless-creature is standing there. what do you do?

(if you dont know what the mimic is, the mimic is resembling a normal human, but without skin. its creepy look does resemble the following: - Extended fingers, longer limbs, buldging empty eyes, and a wide teeth filled smile. although it resembles a happy face, this is only a coincidence and is just how their face is shaped. the mimic contains much more teeth than humans. and their teeth is comprised almost entirely of incisors, with some canine and premolars in the back. This tooth composition is ideal for biting down onto meat and swallowing. chucks hole. A mature mimics diet is comprised entirely of human flesh, because of this they are found mostly around human populated areas. in the first stage, a young mimic separates from the crawl. they are thin, sleek, and only have 4 appendages. in this stage, the young mimic will hunt young animals moving on to larger and larger as they grow. once large enough, it will begin metamorphosis into the next stage of life. once fully transformed, it will resemble the description mentioned in the beginning. it comes into someones house and eats them while they are asleep. the 3rd and final stage, it now can blend entirely into civilization and lure other humans more affectively. but if the mimic receives too much food, it will grow into a larger, more evolved hunter. its proportions will increase in length and its humanoid features will fade away. it grows a thick, dark coating of flexible skin. which is highly durable, and increases in strength the more the elder mimic consumes. this excludes the face, which is now coated in a pale pink skin. the mimics teeth have also moved deeper into the mimics throat, leaving its mouth a toothless grin. it uses the dark hue of its skin to hide seamlessly within a dark environment. its skills have also been heightened. this makes an elder mimic one of the most efficient predators on the planet.)
