River Troll

River Trolls are a distinct breed of troll that dwell almost exclusively within rivers, marshes and other bodies of water, hence their name.

Overview
Trolls are naturally hideous and malformed creatures, among whom a wide variety of different subspecies can be found, but it is the River Troll who tends to be overlooked. Subsisting mainly on fish and the occasional fisherman, these creatures rarely show themselves and tend to hibernate at the bottom of bodies of water

they live on a diet mainly consisting of fish and frogs, although the occasional fisherman who comes upon them usually becomes a snack. The hands and feet of a River Troll are webbed like that of a frog, making them excellent swimmers with exceptional speed. They also have both gills and lungs, allowing them to breathe comfortably above or below water. However, most River Trolls will not venture too far from their habitat as they need to refresh themselves at least every few days, otherwise they may dry up and die.
