A scientific experiment gone horribly wrong: do not approach under any circumstances. It can harbor many forms, generally piggies, but its favorite form is the form of its human victim - a socially inept teenager named Sam Wilson who came into contact with the test subject in 1969 on the Moon mission. MOON PIGS.
