According to the latest Backstage Pass (not available on Disney website yet, checked today)
They are doing a preview of what you might see at the resort this Halloween..

"Dress Up and Chow Down
Celebrate Halloween Time at the Disneyland® Resort with a spirited assortment of souvenirs and snacks! From Disney-inspired Halloween costumes to the popular "pumpkin head" and "witch" hats, you'll have no trouble creating just the right look this fall. You'll also find such fun items as specially created pins, a Mickey Mouse Pumpkin candy bucket and more. And speaking of sweets, sink your sweet tooth into a "pumpkin" candy apple or enjoy a Pumpkin Mickey Demitasse, as special dessert in a mini ceramic cup. Both treats are frightfully delicious! Also materializing this Halloween is a new collectible popcorn bucket - shaped like Mickey Mouse dressed as a ghost!"

All descriptions are done by Disney, not by me. I wouldn't use half those cheesy lines.
Also, it says beginning October 14th when you visit Paradise Pier you can find the Duffy Bear Meet and Greet. You can even purchase your very own at select locations.
