'Pokémon Go' Ultra Bonus Week 1: Start Time, Shiny Sentret, Gligar and More

While Pokémon Go players are trying to catch their Jirachi, the popular mobile game is preparing a special Ultra Bonus Week.

Thanks to the efforts of Go Fest and Safari Zone attendees, as well as players playing around the world, special in-game bonuses as well as new Pokémon will begin appearing in the popular mobile game in September.

The first week of Pokémon Go's Ultra Bonus Week will be Johto-themed, bringing two new Shiny Pokémon to the game as well as the Legendary Beasts to Raids.

Here's everything involved with the Pokémon Go Ultra Bonus Week 1 event including start time.

The first Ultra Bonus week will begin Monday, September 2 at 4 p.m. EDT and will end September 9 at 4 p.m. EDT.


Sentret and Gligar will receive their Shiny Pokémon in the mobile game.

Players can identify a Shiny Sentret by its lighter coloring. It goes from brown to a more orange color. Gligar's Shiny version changes its color from light purple to a more blue color.

Pokémon Go players will need to encounter these Pokémon in the wild before discovering if they have found its Shiny form. You can also identify Shiny Pokémon by the special symbol next to the Pokémon's name.


The Legendary Beasts, Raikou, Entei and Suicune are returning to Raids during the first week of the Ultra Bonus.

The pure Electric, Fire and Water-type Pokémon will begin appearing in Level 5 Raids and players will want to prepare to take them down and catch them using Pokémon that will be strong against them.

All three Pokémon have their Shiny versions released in Pokémon Go so you're likely to have a chance to encounter them this week.


Beginning September 2, special Unknown will begin hatching from 10km Eggs. These Unknown spell out "ULTRA."


A new variation of Eevee is coming to Pokémon Go, and the Normal-type is getting a flower crown to distinguish itself from other Eevee.

From September 1 at 4 p.m. EDT to November 1 at 4 p.m. EDT, Flower Crown Eevee will start to appear as a Research Breakthrough encounter. There is also a chance this special Eevee will appear as a Shiny.

Pokémon fans will want to evolve their Flower Crown Eevees into its available evolutions: Flareon, Vaporeon, Jolteon, Umbreon, Espeon, Leafeon and Glaceon.


Along with the debuts of a couple of Shiny Pokémon, and Legendary Pokémon returning to Raids, Pokémon Go players will be able to incubate their Eggs twice as fast. Incubators will only start hatching Eggs twice as fast when they are used after the start time.

Here are the new distances for each Egg in Pokémon Go:

2km -> 1km

5km -> 2.5km

7km -> 3.5km

10km -> 5km
