They allegedly saw the creature in the afternoon of January 20, 1996. Two days later, another creature was allegedly found lying along a road.
Three military trucks were sent to retrieve it. It was captured by S2 officials (Brazil's military intelligence), and sent to a hospital to be examined.
Eyewitnesses described the creatures as humanoid and three to four feet tall. They had dark brown, hairless skin that was very oily, big triangular heads with three short “horns” on top, and huge red eyes that were vertically oval.
The arms were long and thin, the legs short and thin. They had no obvious noses or ears and only slits for mouths.
