The thorny-butt nobit split from the nobit. It has left the snowy areas of Glicker and now lives on the Krakow Plains and Temperate Forest. Its eyes and ears have gotten bigger to hear and look out for predators. It body has gotten smaller as well as the lumps of fat have become finer and more numerous. Its body looks as if it has fur but it just fat. These are perfect for the cold winds that blow from the South Tundra. The black leaves still warm them up but have become smaller so predators cannot grab on to them. Predators like the tungrab and quill lurker have been known to grab on to their butts and catch them. They now avoid them, what with thorns on their butt that are made from hardened fatty lumps. If they did not have this around their butt-nostrils they could have easily been suffocated by closing their butt-nostril. Like their ancestors they have many babies since they are easily eaten.
