Frost skrayll genetically diverged from the common skrayll during the Great Frosting, where their highly-malleable bodies adapted to changing weather conditions. Frost skrayll secrete a slimy substance that freezes instantly when exposed to air, which the frost skrayll uses to manage their internal temperature. In general, frost skrayll have also learned to use this mutation for increased mobility, allowing them to scale glaciers, burrow through hard ice, or create temporary land bridges.
