Zeugl

The zeugl inhabits the sewers beneath Vizima, feeds on sewage, and grows at an alarming rate. The beast is always hungry, so it reaches out with its tentacles for living creatures and tries to shove them into its huge maw filled with multiple rows of teeth. The zeugl is paralyzingly hideous, foul-smelling, and surprisingly strong for something resembling a rotten potato, so it usually manages to devour its opponent.
