This year's popcorn bucket at Disney is the Scary Teddy! (AKA the Mickey Mouse cameo)! It opens when you pull the head back and grab the popcorn from its mouth.
This year's Nightmare Before Christmas-themed popcorn bucket has The Mayor of Halloween Town in his car, with Lock, Shock, and Barrel! These will exclusively be available at Mickey's Not-So-Scary Halloween Party, which will last until November 1st!
