Mickey's Not So Scary Halloween Party 2017 Mystery Collection - Tigger Chaser. Tigger, from Winnie the Pooh, is dressed in a purple pirate's hat with a white skull and crossbones and a blue and red vest. He is holding a green glitter filled candy bag with the MNSSHP 2017 logo. This pin is one of four chasers in a twelve pin mystery set released on August 25, 2017, for Walt Disney World's Mickey's Not So Scary Halloween Party 2017. Each box contains two randomly selected pins. Due to a randomization issue as well as a manufacturing flaw, these mystery boxes were pulled off the shelves on the first night of the 2017 Halloween Party. It is not known if they will be reissued at a later date. Chaser pins for this set are LE 1000 each.
