Congrats to Gamedev's own TANSTAAFL, who sent me the winning name in my ad-hoc contest from a couple of days ago.
Duce Caucho
It got a chuckle outta me, so I'm declaring it the winner. Babelfish doesn't agree, though, saying "goma pato" is correct. Any Spanish scholars out there?
Second place goes to "April" (whom I recognize from the GD chatroom). She went after the ducky's dancin' style and named him "Astaire D. Duck but his friends call him Cha Cha."
He does look like he's havin' fun down there. Wonder if he ever gets tired?
