The fourth season of Pokémon Go, the season of mischief has arrived.

During the Season of Mischief, players will have a special search line to meet Hoopa. The season will also include the return of the Psychic Spectacular and Fashion Week events. Besides, Giovanni, the boss of Team GO Rocket, is missing ?!

This season also coincides with fall in the northern hemisphere and spring in the southern hemisphere. In addition to Deerling and Sawsbuck changing their shapes to match real-world seasons, you can expect a handful of season-appropriate Pokémon in their respective hemispheres.
