Pretty Little Liars just shocked fans with a crazy season finale filled with surprises and revelations...and of course, lots of new questions.

We won't say anything about it in case you haven't seen the episode yet, but let's just say it was a good one.

The promo for the special Halloween episode is already up, and it looks like this one is going to be good too. It airs on October 23^rd, and until it airs there's a mini web series that centers around a Halloween store in Rosewood.

Check out the preview below!
