Memory:Snake from Beyond

At first appearing to be a huge variety of water snake, this beast is revealed as something corrupted into a horror all its own. Easily twice the size of a water snake, its surface is much denser, perhaps due to its deep-water origin, where it had to endure much greater pressures than in this easy realm. It is fast for its size, attempting to bite if it cannot wrap its victim in its body, drowning and crushing them with its water essence.
