The holiday 2017 event is currently underway in Pokémon GO. As part of this celebration, a familiar festive Pikachu is back and more Ice-type Pokémon are now appearing around the world, as well as additional Water-type and Ice-type Pokémon originally discovered in the Hoenn region in the Pokémon Ruby and Pokémon Sapphire. As a special bonus, the first PokéStop you visit each day between December 22 at 1 p.m. PST and December 25 at 1 p.m. PST will award you a single-use Egg Incubator with your first Photo Disc spin, so make sure to check in every day to collect an incubator.
Delibird can now be found and caught in Pokémon GO, as well as 20 additional Water-type and Ice-type Pokémon originally from the Hoenn region. Shiny Snorunt has also begun appearing around the world in Pokémon GO. Lure Modules last for six hours when activated until January 4, 2018. In addition to all this, special discounted boxes with Super Incubators, Lure Modules and the all-new Star Pieces are now available in the in-game shop until tomorrow, December 25.
