The cheer and joy of the holidays is coming to the world of Pokémon GO, as the Delivery Pokémon, Delibird, returns for Pokémon GO Holidays 2018!

• Starting on December 18, Ice-type Pokémon will appear more frequently in the wild, including Jynx, Sneasel, Swinub, Snorunt, Spheal, and Snover!
• Certain other Pokémon are also getting into the festivities—you might see holiday-ready Pokémon, such as a Pikachu wearing a festive hat.
• Pokémon such as Smoochum, Azurill, and Munchlax will have a greater chance of hatching from 7 km Eggs.
• Trainers will also earn a free single-use Incubator once per day via spinning a Photo Disc on a PokéStop.

• December 18 - December 22: double Candy for catching and transferring Pokémon.
• December 22 - December 26: earn double Catch Stardust.
• December 26 - December 30: earn double XP when you catch Pokémon.
