The nobuck evolved from the nobomaton. Since the vicious sauceback and other predators were getting more effective, it too evolved in the arms race known as evolution. It has gotten smaller, but lighter and more agile. Rather than a rhino-like build it is now deer-like. Its ears have improved as well as its eyes, splitting into 4 separate eyes. The front pair are great for seeing in the light, while the back 2 are great for in the dark. This means one pair of good night-vision eyes are always ready to see in the dark shadows of the tree-plent cover. Due to this lack of light, its back leaves have shrunk. This helped with it move through the forest without snagging on as many branches. Its camouflage has also adapted. Due to so few purple plants in comparison to green plent-trees, it now has a green and brown coloring with some pink spots to mimic pink stickyballs. It also has evolved footpads to better grip the soil when running.
