To celebrate the Sinnoh region, a special event featuring Pokémon from the fourth generation is taking place in Pokémon Go until Feb. 10 at 10 p.m. in your local time.
The event features Field Research tasks, with some of them giving out Sinnoh Stones, an evolution item needed to evolve many of the region’s strongest Pokémon.
In addition, Pokémon like Budew, Combee, Bronzor, Gible, Riolu, Hippopotas, and Mantyke will be hatching out of seven kilometer eggs. Niantic’s announcement notes that only Pokémon from the Sinnoh region will be coming out of these eggs, so this is likely the best chance to grab a rare find, like Gible or Riolu.
Hippopotas and Riolu are also appearing in the game Shiny for the first time.
Based on The Silph Road subreddits’ reports, it appears that Bronzor, Chimchar, Gible, Piplup, Snover, Turtwig, and Hippopotas are also spawning more frequently in the wild. If you manage to grab a Chimchar, Turtwig, or Piplup with good IVs, consider holding on to it before evolving. It’s very likely that their Community Day legacy moves will return in December, as they have in the past.
