Pokémon Go developer Niantic took to Twitter to confirm that the Santa Pikachu inside the game can evolve to become Santa Raichu.
Well, technically Niantic calls the character Holiday Pikachu, but to-may-toes, to-mah-toes, eh?
Trainers, Raichu will have a festive hat if evolved from #HolidayPikachu, and both will keep the hat permanently even after Dec. 29, 2016.

You have until 29 December to nab the festive character.
Pokémon Go is available on iOS and Android. It was recently updated to include generation two Pokémon characters.
