Part 1 of Pokémon GO‘s Halloween 2021 event, Halloween Mischief, starts October 15th 2021 at 10:00 am local time. ‘Creepy Companions’, the title name for the first part of the event, focuses on Poison- and Psychic-type Pokémon, the same typing as the newly released Galarian Slowking, who is making its debut in Pokémon GO. You can find out how to obtain one by visiting our guide on ‘How to get Galarian Slowking in Pokémon GO‘.

In this guide to Pokémon GO’s Halloween event, we’ll cover everything you need to know to take full advantage of the event, including shiny Pokémon, new costumed Pokémon, Pokémon spawns, Field & Special Research tasks and more.
