This creature resembles a snake with thin,
projecting legs,
the rear set webbed for swimming.
About half its length is neck and head.
The head and jaws are long,
the latter being filled with many sharp teeth.
Compared to its body the head is small.
This carnivore lurks along riverbanks
and swamp edges, prowling through the waters. When attacking by
surprise, it strikes at +2 to hit. If the victim is under 500 pounds in
weight, the monster will drag it into the water to further attack and
devour it.
