This is an early push of content for next week.
Ambassador Amnerys posted on the official forums:
We will bring the Free Realms servers offline on Thursday, November 15, 2012 at 8:00 a.m. PST (San Diego Time) for a Game Update. Anticipated downtime is around 1 hour.
Content from this update will not unlock until next week. We are publishing it early (but content will be locked) to prevent doing an update during the holiday week.
