A worm whose body has a brain-like texture and his head is made of fire. Its head also has four thin feelers with a luminous yellow tip each. The worm has the ability to increase the temperature of complex lifeforms that can have a fever, such as humans. He enjoys frying brains in this manner.
The Feverworm died in the marrow dungeon when used in a puzzle that exposed him to Gasworm's flammable gas.
In Awful Hospital.
