Yamask Pokémon GO to Arrive During the Halloween Event
The Ghost-type Yamask will finally be introduced. Yamask will arrive at the same time as its Shiny form. Yamask evolves into Cofagrigus, whic means you will be able to find a shiny Cofagrigus.
As with every ghost-type Pokemon, they spawn more at night, so be prepared to make some night runs during the event.
The Halloween event will end on Nov. 1 at 4 p.m. ET.
