Yes there's a Bieber zombie.
A long time ago, or so it seems, myself and Ed Altorfer decided we wanted to make a game... in a weekend.  Zombie Defense was that brain child. It was a quick and easy game, 2D and my first game published on a mobile device, the Windows Phone to be exact.   For 0.99 cents i think its a pretty decent buy.  Either way, I was the lead (only) artist with Ed the lead (only) programmer, lol.
