The Mississippi Mudcat is a creature that was given life by the Chinese success in bombing and irradiating the source of the Mississippi River. One of the primary Minnesota targets was the Lake Itasca area. Lake Itasca is the source of the Mississippi River, the great river that bisects the American Wasteland. With radiation flowing down from the river's source, much wildlife was wiped out. One thing to survive, however, was the Mississippi Catfish. This animal not only survived, but millions of years of evolution allowed it to adapt and thrive. The already large size of this fish increased to the point where it could remove a man's arm with a chomp of it's powerful toothy jaws. It's side fins grew stronger and claws formed, allowing it to drag itself with speed and aggression across the muddy bottom.
Perhaps the most disturbing new feature of this river terror was its gills. The gills now had the ability to breathe in oxygen directly from the air, giving this fish the amphibious trait of being able to emerge from the water and survive for a time on land. Up and down the river, report of these aggressive creatures spread by backward wasters, until finally, they began emerging in Polis itself. This lead to increased protective measures around riverside developments as Brahmin, people, and anything else edible was pulled into the depths of the Mississippi. With the presence of the Mississippi Mudcat, the areas around the water have become a dangerous and unpredictable place indeed.
The Mudcat's appearance doesn't differ very much from a normal catfish. Notable differences are the size and the clawed, elongated, and strengthened frontal appendages. The Mudcat's size varies from 8 to 15 feet long and can weigh up to 1500 pounds. The flat, wide head and long mouth are bristled with whiskers to seek out prey, as the Mudcat's sight leaves something to be desired. The inside of the mouth is lined with needle-like teeth. The front fins have mutated into long limbs that the Mudcat uses to move along the ground. The Mudcat moves along the ground by dragging itself along the mud with its front limbs. It moves surprisingly quickly for its size, but it's quickness fades as distance increases, because its massive size can only move so quickly so far. Nevertheless, surprise, and power make the Mississippi Mudcat a predator to be feared on the banks of the Mississippi River.
