Slurm Queen

The Slurm Queen lives in the Slurm Factory on the planet Wormulon. She produces from her behind what is the secret and only ingredient, squirted directly into Slurm cans in the factory. She tried to kill Fry, Leela, Bender and Slurms MacKenzie when they tried to expose the secret of Slurm. She is presumably immortal, as she can drink her own excretions.

The Slurm Queen was also present at the Young People's Choice Awards in 3011, where she covered Leela in Slurm.
