Operation Halloween Costumes are a set of individual character accessories that were first introduced during the Operation Halloween event in 2019. For some characters, although the accessory can be purchased in the shop at any time of the year, the accessory is seasonal due to the fact that the Halloween Candy currency used to purchase it is only available during Halloween Events. For other characters, the accessory is seasonal as it has only been made available during events, and there is currently no means to unlock it.
