How about a blood-sucking Pico Bandito vampire? Instead of using him as an enemy, I had the idea to offer him and different characters as in-app purchase sometime in the future. It would be a pack with a bunch of different "skins" like a vampire and cowboy and robot etc. That way I could generate interest with a free app promotion thing and still make money. My main priority right now though is to get more levels done.
OMG U could sooooo call him either Vampico or Pico Vampdito!!!!! (Or Rblacula (SEE WHAT I DID THERE?))
