If you put a frog in boiling water, it will jump out. If you put a frog in cold water and slowly heat it up, you're being weird. If you put a frog in the arcanely-tainted waters of the Lycaeum, it'll eventually turn into one of these big aggressive amphibians, yet another reason why it really isn't safe to be down there at all.

Where it spawns
The LycaeumHealth here is the base figure the game spawns it with. Enemies gain health every minute the clock runs, Curse multiplies it again, and Inverse doubles the whole stage before any of that.
