Fishing Bat vs. Catfish

Not often enough does a setting show off what happens when creatures attack one another.  This can be a great way to throw a tougher creature at an adventuring group, in that if they stumble across a battle between creature-rivals, the surviving creature can have been injured and pose less of a threat if the party then takes it on.  Over on the National Geographic YouTube channel is a cool video called "Fishing Bat vs. Catfish."  Enjoy!
