Swamp bears, called such by wilderness dwellers but no relation to that species, are classified as diprotodonts by animal experts. A lesser variety of megafauna, swamp bears are browsers who live near water, and flee to the nearest water-hole when attacked, if they are able. Males, the statistics of which are listed here, will charge at predators to drive them off so females can flee; females have 6 HD and do not possess the Improved Bull Rush feat. Diprotodonts have a cartilaginous posterior and no visible tail, and are thus harder to hit when in retreat, kicking with hind claws at pursuers. Smaller subspecies of swamp bear (of Medium size and 4-5 HD) are known to be burrowers and hole-dwellers instead of water-loving, and have a burrow speed of 10 ft.

On Porphyra
Swamp bears are common in the regions of Giant’s Retreat and the Jotun Forest, along Hunter’s Creek and the Trollwater. Trolls find them especially delicious and eat them whenever they can; swamp bears can smell a troll a mile away. They are hunted by giants and ogre lions alike in both places.
