Each Model Citizen (employee) at LEGOLAND has a minifigure on their badge. If you like it, you can trade for it. There are a few caveats. The entire minifigure must be traded. You can't just swap a torso for a torso. The minifigure must be LEGO branded. So, although custom minifigs are a fun thing to own, you can't trade it. And LEGO Friends Minifigures aren't able to be traded since they don't properly fit on a Model Citizen's badge. You can either purchase a minifigure at a gift shop within LEGOLAND or bring one from home to trade.
