The flune replaced its ancestor the turtsnapper in the Huggs-Yokto Desert. With many predators around it needed to improve its armor. It now has a segmented shell which can be turned into a ball. This not only is impenetrable to predators but can help it quickly roll down sand dunes to escape. It has shrunk in side as well. Since they are smaller they do not sink in the sand as easily when rolling. Its coloring blend in whit the rocks and purple flora around. Its beak allows it to graze on normally uneatable grasses like spikeblades and quillblades.
Like its ancestor it can survive during times of famine by digging a hole and hibernating in it. Since water is scare it must migrate to BioCat River and lay its eggs in the river when it is flowing. The eggs grow up quickly eating the local river flora such as Salt Grass and River Saltgrass. Once they grow into adults they will make their way into the harsh desert. After mating the females will return to the river to lay their frog-eggs there, thus completely the cycle.
