Minifigure Monster Madness - Lumberjack to Werewolf

So, maybe I’m just a total noob, but I recently learned about this lumberjack who turned into a werewolf?! I guess this dude Kel was just out chopping down trees like any lumberjack would, when all of a sudden he was attacked by a vicious werewolf, becoming one himself? Or was he always a werewolf and the designers just waited four years to reveal that fact? I am so obsessed with this amazing little minifigure secret. There MUST be more secrets like this! Does anyone know any? If so, PLEASE...
