These light green/dark green mottled eel-like creatures are two to three feet long and prowl the waters looking for poor helpless creatures to attach to and drain them of their blood. They use their round sphincter-like mouths and raspy teeth to latch on and suck the blood from their victim. They will drain up to 20 hit points of blood before being satiated and dropping off their victim to return to their lair and digest their meal. They will also use their mouths/teeth to chew holes into the side of boats, causing the boat to take on water and sink; thus, making it easier for them to attain their meals. With small boats (i.e. rowboats), it will take them 1-4 rounds to chew through. Larger, thicker boats and small ships, it will take them 1-4 turns. They can be found in both fresh water and salt water.
