The Zombian Houbdlizard is born grey and whole and perfect but as they age their body even tho they are actually alive starts to decay and slightly develops a rotting/moldy pattern. Their skin loosens and falls off in some areas and or just dangles, their bones could poke out along with some organs like their intestines, and their teeth and toes will fall out. Their mating is rather odd, the male and female are both dominant and will bite and claw at each other  to get a good grip. They do need to continuously eat considering that they actually burn all of their energy quickly, which is why you never see one without a bloody mouth. Some go blind in one eye or both or sometimes never go blind. The one with the most bodily damage is actually the oldest. Their favorite things to eat would have to be hearts, livers, gizzards, throats, spines, and of course BRAINS, they really love mammalian brains due to the fatty acid known as DHA (Omega 3 Fatty Acid.) They can be slow but when they smell a rotting corpse they will start running to it and gorge upon it. Do not attempt to fire bullets at them as you can see ZOMB was a test subject to see as to how much they can handle, he has survived the bitter cold, blistering heat, deep underwater, and has survived gunshots. You may be wondering as to why they don't get sick from all their open wounds or at least gain an infection, it is due to secreting a special anti bacterial slime that they naturally produce to protect themselves from the elements, it doesn't wash off with water nor does it dry up when it's hot or cold. Despite the pungent odor they tend to produce or the disgusting slime they drip from their body they can be rather cuddly.
