Someone might have beat me to this, but:
I just saw this today and it got me jazzed all over again for Halloween Time (my favorite time of year)
It features some of the main Disney villains (Maelficent, Jafar, Queen of Hearts, Evil Queen, Hades, Hook, Cruella, Ursual) sitting in the castle excited that b/c it's Halloween Time all our Disneylands are belong to them!
It shows Mal on the Haunted Mansion, Queen on Hearts on Tower, Hades setting off the fireworks, etc.
The animation is awesome!!
The only way to get to it is to go to this link: Halloween Time at the Disneyland Resort
and click on videos and it will start playing automatically
There's more to the site talking about the various activities associated with Halloween Time and there's also a new "Treasure Hunt" that looks to be close to the same idea as the Muppet Labs Sacavenger Hunt from last year.
I am so Excited!!!!
