How to get the secret event title.

Wear the skull, the fangs and the Halloween title <<Halloween 2013>>. I don't know it this is affected by customized colours in the items or having other items on but to be safe, I wouldn't.
Then on the candy collection map for the main Halloween event, go right to the bottom and inside should be a painting on the wall. There is actually a ledge to climb onto so it's pretty easy to be right in front of the painting which is the place you want to be. All you have to do once you're there is push the Sleep emote on the mini menu in your tool bar, and say 'vampire'. You should then recieve your title.
