The Pokémon Go Sinnoh region celebration event begins Friday, February 7 at 8 a.m. to Monday, February 10 at 10 p.m. local time.


Two new Shiny Pokémon are making their Pokémon Go debuts, and one is one of the most rare 'Mon in the region.

Shiny Riolu and Shiny Hippopotas will begin appearing in Pokémon Go when the Sinnoh celebration event starts. While it's not clear if Riolu and Hippopotas will appear more frequently in the wild - the latter is more likely - both will appear more frequently in 7km Eggs when the pool changes with the event.

Both Pokémon may also be rewards for specific research tasks, but we'll update when we learn more.

Shiny Riolu changes its coloring from blue to gold, while Shiny Hippopotas' coloring becomes more saturated.


There will be new research tasks that go live when the Sinnoh event begins. Niantic confirmed on the official Pokémon Go blog that Sinnoh Stones will be the reward for at least one task.

Here's a running list of confirmed research tasks for the Sinnoh event:

  • Catch five Kricketot - Combee
  • Win a Raid - Hippopotas
  • Evolve a Pokémon using a Sinnoh Stone - Cranidos
  • Hatch five Eggs - Sinnoh Stone
  • Catch five Turtwig, Chimnchar or Piplup - Stardust (x1000)


All 7km Eggs during the Sinnoh celebration event will hatch only Gen 4 Pokémon. The official Pokémon Go blog confirmed the following Pokémon will hatch more frequently in the latest change to the Egg Pool:

  • Budew
  • Combee
  • Bronzor
  • Gible
  • Riolu
  • Hippopotas
  • Mantyke
  • Buizel
  • Cherubi
  • Bonsly
  • Shinx

Perhaps now trainers can find Gible more frequently than they currently can.

Sinnoh Stones can be collected easier through research tasks during the event. Trainers may want to stock up on them to evolve the following Pokémon:

  • Electabuzz -> Electivire
  • Magmar -> Magmortar
  • Rhydon -> Rhyperior
  • Lickitung -> Lickilicky
  • Tangela -> Tangrowth
  • Murkrow -> Honchkrow
  • Sneasel -> Weavile
  • Yanma -> Yanmega
  • Aipom -> Ambipom
  • Misdreavus -> Mismagius
  • Porygon 2 -> Porygon Z
  • Togetic -> Togekiss
  • Roselia -> Roserade
  • Kirlia (male) -> Gallade
  • Snorunt (female) -> Froslass
  • Dusclops -> Dusknoir
  • Magneton -> Magnezone
  • Piloswine -> Mamoswine
