This is the fourth pin in the 13 pin Countdown Series for the 2016 Pixar Party Pin Trading Event. It is a purple toned hinged pin. The inside has a sculpted image of Boo dressed in her monster costume from the Pixar movie Monsters Inc. The front is a purple stained glass ball with a silver star that is synonymous with the opening scene from every Pixar movie where Luxo Junior stomps on a rubber ball. A purple banner reading "It's a Celebration" over more purple glass with the words Pixar and 2016 runs across the bottom of the pin. It was only available for purchase at Pin Traders in Disney Springs.
