Pokémon GO boasts the ability to capture most of the National PokéDex in one single game, bringing in Pokémon from all generations (and many of their Shiny variants). But for much of the game’s existence, Shiny starter Pokémon have been hard to find.

Chespin will finally get its Shiny variant in Pokémon Go during its Community Day on Jan. 7 from 2 p.m. to 5 p.m. local time. During this three-hour period, Chespin will spawn more frequently, giving you plenty of opportunities to catch it.
