Dungeon Runners: Dungeon Runner's Gold-Excreeting Bling Gnome Spotted:
The Bling Gnome is a pet of sort that runs around in the game as you play picking up all of the gold dropped from the baddies you kill while playing the free-to-play massive game. The gnome can also be told to pick up dropped items that aren't rare and eat them. He then poops out gold as a reward... seriously.
I love this idea, it saves all of the hassle of having to go back to town and sell off the crap you horde while out in the wilds adventuring.
