Now prey to the beaked areal killer plent, some plentutri tried living where the plents could not reach, and the ground became an obvious choice, as areal killer plents could crash into it and never get up again. The ancestors of the white-backed Plent managed to survive the Southern Tundra. There, there were no ground predators and firpalms to eat. Some still falling victim to the killer plents, they became much snow-colored, while wings becoming much darker to absorb lots of light. This made them just that little harder to see (not having the tell-tale shape of a flying plent) but not unable to get sunlight. Like the noboms, the wings became much more like solar panels, the reactions inside them primarily giving out heat. This kept the plent warm, but it also has to eat much more a day. They have also grown a bit, size really not mattering so much anymore. Being of an airborne nature, the white-backed plents also managed to spread into the alpine regions (where, during winter, they were virtually the only thing eating the firpalms) and both tundras. They are usually bigger towards the south pole, and smaller towards the north pole, where they are a lot less common. When not in terrain covered by snow they can be seen and then eaten very easily, thus is is rare to see one out of its habitat.
