Pokémon GO players will soon be able to visit participating LEGO Stores for a special in-person event featuring a stamp rally, event-themed Timed Research and exclusive avatar items. Trainers who take part will also have the chance to encounter Shiny Pikachu, with some lucky players able to find one featuring a Special Background. The collaboration adds another location-based experience to Pokémon GO, rewarding participants with exclusive in-game content while encouraging players to explore participating LEGO retail locations.
