As you enter a dungeon, you can almost smell the unmistakable scent of decay. You slowly make your way down the path. In the distance, you hear a slow scuttling coming towards you. It’s a rat: Not just any rat, but one of those super-sized dungeon rats. You raise your sword to deliver the killing blow and, as you look down upon the rat’s quivering body, you see that this simple rodent was carrying a healing potion and a shiny new scimitar. How convenient!
