A Hydra Pod is a floating pod, found deep in the lake of The Mire. Destroying at least three of these orbs (in a single world) will summon The Hydra. This can be done using any hammer or explosives. They are the Mire counterpart to The Inferno's Dragon Eggs.
Multiple Hydra Pods are found in the Mire, each located at the bottom of the lake, surrounded by Depthstone. While mining Depthstone requires at least a Nightmare Pickaxe, Depthstone can be converted to normal Stone Blocks with Purification Powder, and mined with a lower-tier pickaxe. Alternatively, explosives can be used to destroy Depthstone.
- "The contents spill from the broken pod. Nasty." (When breaking the first pod)
- "You hear hissing somewhere nearby" (When breaking the second pod)
- "You hear hissing, but it scuttles away into the fog..." (When breaking the third pod during the day)
