Overview
The Worm is a huge dragon who gained a castle, land, servants and possessions through earlier battles. By the time Mikko’s fox approaches, he has spent years without a challenger and become fat and unable to fight as before. The fox pretends that the king and a great force are advancing to destroy him and his people. Frightened, the Worm requests assistance and proposes hiding underneath linen in a shed while the fox locks it outside.
Instead the fox sets the locked shed on fire, reducing the Worm to ashes. His estate passes into Mikko’s apparent ownership after the fox intimidates or persuades its workers to recognise the human as their master. The text does not describe wings, a head count, fire-breathing or a transformation into a smaller animal. Worm is the dragon’s name within this particular story; no identity with unrelated named worms or later fantasy dragons is established.
