THERMALUNK - The Lumbering Furnace
This specialized variant of the Smoldron is less mobile and more defensively oriented. It can release an impressive fireball from its vents or detonate in an emergency, but often keeps the enemy at bay with only its "heat walls;" invisible rings of stationary, concentrated heat the creature can project for up to half a mile.
When their services aren't necessary, Thermalunk deflate much of their body and rest in a cylindrical bundle, springing to full size upon command. They are mildly afraid of the dark.
