Pokemon Go's Halloween 2021 celebration is here. The event kicks off today, Oct. 15, and is divided up into two parts, each of which features various Halloween-themed Pokemon and activities, including new ghost Pokemon from the Kalos region and the next chapters of the Misunderstood Mischief Special Research story. Here's everything you need to know about Pokemon Go's Halloween 2021 event.

Event-long features

Although the Halloween 2021 event is broken up into two parts, some features will be available across both. First, there will be new Timed Research tasks to complete, as well as a new Special Research story called What Lies Beneath the Mask? The following bonuses will also be active throughout the entire event: 

  • 2x transfer candy
  • 2x hatch candy
  • 2x catch candy
  • Guaranteed candy XL when walking with your buddy

On top of that, game developer Niantic will offer new avatar items in Pokemon Go's shop, as well as new stickers and special event bundles. Each leg of the event will also introduce a new portion of the season-long Misunderstood Mischief Special Research story. Finally, the Halloween Cup will be underway in the Go Battle League, and the game's nighttime music will be replaced by a remix of the iconic Lavender Town theme from Pokemon Red and Blue.

The second part of Pokemon Go's Halloween 2021 event runs from Oct. 22 to Halloween itself. During this portion, ghost- and dark-type Pokemon will appear in the game more frequently, and you'll have your first chance to get four new ghost Pokemon from the Kalos region: Phantump, Trevenant, Pumpkaboo, and Gourgeist.

Alongside Pumpkaboo and Gourgeist, Niantic is introducing a new size mechanic to Pokemon Go. Just as in mainline Pokemon games, Pumpkaboo and Gourgeist can appear in various sizes, and the ones you encounter in Pokemon Go will visibly vary depending on how large or small they are.
