This is the Land Whale or walking cloud. They can grow up from 300 to 400 feet and weigh up to 50 tons but have vacuum hollow bones, which gives it some weigh relief from it full 60 tons. It does not look fast but can move a max of about 79 mph. It has gill like slots in its neck so to intake and separate water and air born microorganism, which live in this planets atmosphere, and consume them. The neck actually leaves the body at the chest, instead of the back, to better reach the ground and hardly ever raises it above its body. It has dark skin on the top of its body to resist sun radiation. It can also eat trees and drink water. Some people have found a way to build cities on it for natural protection and the trees can be native to the backs of the beasts in which it can gain energy from them. That is all.
