The Shiny Tapu Koko event has gone live via Mystery Gift in Pokémon Sun and Moon for players in Europe and Australia. It can be accessed by connecting to the Internet option in Mystery Gift. This Shiny Tapu Koko matches the Shiny Tapu Koko from Japanese distribution earlier this year. There is currently no word on a North American distribution, but stay tuned for any updates.
