Coaxing a Hydrhis seedling out of its shell is just about as daunting as taking care of the end product. Once sprouted, the surrounding environment will imprint itself on to the young creature. A neglectful or careless owner will result in the raising of a mischievous Hydrhis while a loving owner will raise a more docile one. Regardless of the environment, all Hydrhis are bound to share one trait in particular: hunger.
Hydrhis are carnivorous plants that reside in Ark's mountainous regions. Some may expect a little more from a draconian creature, but Hydrhis are rather short in stature (with the tallest recorded height being 0.9 meters). All of the heads upon a Hydrhis share the same "brain" and thus do not think independently for themselves. However, further research has revealed that the many heads do specialize in displaying a Hydrhris' various emotions; one head may express joyfulness while another deals with negative feelings.
The voracious appetite of Hydrhis has led to the creature's name becoming synonymous with someone who has gluttonous behavior. Cetopia and Serpede are favored sources of food in their diet.
