River Troll  

River Trolls are green coloured trolls with huge fangs, wide ears and blue scales along their body. They live in the marshes, swamps, lakes and rivers of the Old World. River trolls are noted for the fact that even compared to normal trolls, they are exceptionally disgusting and smelly, being quite possibly the most pungent creatures to live in the Old World. The stench of rotten fish and other questionable matter that emanates from them is so powerful that it can bring a man to his knees.

It is very difficult to remove a River Troll once it has become entrenched in a body of water. Like others of its breed, the River Troll can regenerate all but the most hideous wounds, and can spew acidic vomit at anyone.
