Galarian Yamask may be making its debut in Pokemon GO alongside the 2020 seasonal Halloween event.

Niantic Labs is set to make their Pokemon GO Halloween event announcement any moment now. The official Twitter account has been teasing the event since the beginning of October. Now, data miners may have uncovered exactly what awaits them during the holiday festivities—including Pokemon debuts, special research stories, and more.

Here's what you need to know in order to catch Galarian Yamask.

Galarian Yamask Pokemon GO: How to Catch

The prolific data miners of the popular Pokemon fansite, Silph Road, may have discovered the would-be implementation of Galarian Yamask and the wild release of Spiritomb. Veteran trainers may remember the latter Pokemon from Halloweens-past.

According to exclusive Halloween research dialogue, trainers may be able to encounter Galarian Yamask as part of this year's special research story. The story, itself, will be called "A Spooky Message Unmasked" and makes several references to a "particular Yamask, which...hails from the Galar region and looks almost like stone, not a mask."

Trainers will also be tasked with evolving their Galarian Yamask into a Runerigus. Fortunately, all candy counts in common among the different forms of Pokemon. Players who may have had luck finding Unovian Yamasks this year could have an easier time evolving their Runerigus.

Additionally, trainers could possibly encounter Galarian Ponyta and Rapidash. The chances of a shiny are currently unknown.
