Swimming through the swamp is an extremely large creature. Although most of it is below the surface, its large, domed patterned shell is still visible.

The demon turtle blends in especially well in murky swamps. Sometimes these fiends are mistaken for large mounds of earth.

Shell Shocked. Their distinctive shell patterns can warn of danger but are often covered by dirt. The shell is extremely strong and provides the monster with ample protection.

Toxic Turtle. Most demon turtles have been found in warm swamps, but they have been discovered in other regions as well. They are survivors and use violence to get what they want.

Swamp Snacks. Demon turtles feed on whatever they can find in the gloomy region. They usually take over an entire swamp and live at its center.
