A big dragon’s got to be like a walking oasis – thick, heat‑tight scales that block the sun, a layer of fat for insulation, and a huge lung capacity so it can hold breath during the sand rush. It can tuck its wings close to keep wind from whipping the face, and use a special, almost invisible mist from its nostrils to keep sand out. When the storm hits, it dives into the dunes, burrowing a shallow hole, breathing shallowly, and waits it out until the wind dies. That way it stays cool, dry, and ready to roar again once the sky clears.
