The Pokémon GO Halloween 2017 celebration is officially underway, marking your very first chance to encounter Pokémon that were originally found in the Hoenn region of Pokémon Ruby and Pokémon Sapphire, including Sableye, Banette and others. They are joined by more spooky Pokémon such as Gastly, Cubone, and Drowzee in greater numbers when you head out into your neighborhood. You may also want to keep an eye out for a special costume-wearing Pikachu for a limited time. The special Mimikyu’s Disguise Hat is also now available in your avatar’s Style section.
Halloween is all about candy, and the Pokémon GO celebration is no different. During the Pokémon GO Halloween event, all Candy rewards (except for Rare Candies) will be doubled! Plus, there are opportunities to stock up on supplies with discounted special boxes in the in-game shop. The Pokémon GO Halloween event began today, October 20, and runs until November 2 at 1 p.m. PDT. To see a screenshot of the new Mimikyu’s Disguise Hat, click here. Also as part of the Halloween 2017 event, new Shiny Pokémon are now available in Pokémon GO, including Shiny Sableye and Shiny Shuppet as shown in the screenshot above.
