A threeheaded hydra, not the one from greek mythology though. A death hydra is a reptilan monster marked by undeath but dead itself. Its blessed by necromancers and is used as a pet or a guardian.
Death Hydras are gluttonous, feral monster that drools acidic saliva and are ready to eat anyone that gets to close. They reek with the smell of death and getting close to one can cause mortals to vomit and feel really ill. Only to be granted a crunching death by three toothed maws.....
This was just me playing around, it was originally going to be a regular, not undead themed hydra but since i listend to the theme for Wrath of the Lich king, why not.
