Putricide's Laboratory of Alchemical Horrors and Fun

Putricide's Laboratory of Alchemical Horrors and Fun is the main area of the Plagueworks in which Professor Putricide preforms his experiments. It is from here he watches over his "sons", Festergut and Rotface.

It contains a secret trapdoor that leads to Putricide's Secret Lab, which can only be unveiled during the unholy death knight quest to gain The Bonereaper's Hook, an hidden appearance for Apocalypse.

This is the longest named zone found in the World of Warcraft.
