Ten feet tall and four feet wide, the Flatwoods Monster isn't of this world. Its body is composed of a shiny, metallic substance not found on Earth and it emits an acidic smoke that billows out from its cylindrical body (which causes the eyes, nose, and mouth to burn). Even though the hazy atmosphere obstructs vision, its bright, robotic eyes can be seen quite easily. After a high-pitched, mechanical screech, the entity typically disappears, leaving behind a nauseating, burnt smell and puddle of thick, black liquid.
