Jade barroth

the jade Barroth is a blue and green subspecies of Barroth that lives in the Tundra. Known as Ice Crushing Wyverns, they cover themselves in snow for protection, in much the same way Barroth cover themselves in mud.  The Jade Barroth is capable of performing U-turn charges through the snow, head slams and shaking off its snow to hurt hunters. The Jade Barroth's crown is also somewhat larger than its desert cousin; this may be to warm the air it breathes.
