Bond with your Buddy Pokémon during the Buddy Up event!

Trainers, Time to buddy up and enjoy an event together with your Pokémon GO buddy! Spend time with your Buddy Pokémon with special bonuses, like decreased walking distance for earning Buddy Candy and hearts with your buddy.

Alolan Meowth, Chansey, Eevee, Feebas, Lillipup, and Joltik make great buddies and will appear more often in the wild. Woobat will also be making a special appearance!
