In times of war, The Ancients flooded the rivers and lakes of their foes with all manner of baleful beasts...

...BUT THEY DIDN'T ALWAYS STAY IN THE WATER!!!

An unholy blend of piraña, grunion, and flying fish, the 2' long all-terrain piranha is yet another aquatic abomination unleashed by the Ancient bioweapons program known as  Operation: Razorteeth.

While perfectly at home in any type of water—fresh, salt, and even polluted—they often take to the air to hunt terrestrial prey.  All-terrain piranhas can survive indefinitely on land, and often lurk in ambush from inside the carcasses of half-devoured victims.

Ancient canisters of all-terrain piranha eggs may still be buried in the murk and mire of the Mutant Future.  Woe be to any settlement whose waterways become infested....
