A Natnomissa is a 3 headed dragon that eats toenails covered in chocolate syrup. The undescribable creature enjoys playing Neopets and flying into peoples houses. It prefers eating heads of baby Llamas rather than listening to elders. The Natnomissa can be very dangerous and if spotted, should be reported to the ASPCA. It has been spotted in the Hudson River but could even be found in your toilet. It has a yellowish apperance and has been known to carry Mad Cow Disease.
