The first wave of Pokemon Go‘s Ultra Bonuses have arrived. This batch of rewards will be available until September 9, and it includes the return of three fan-favorite Legendary Pokemon, as well as the debut of a couple of new Shiny variants.

First, the three Legendary dogs from Pokemon Gold and Silver–Entei, Raikou, and Suicune–are appearing again in Raid Battles, as are a few other monsters originally from the Johto region such as Tyranitar, Ursaring, and Skarmory. On top of that, you’ll have a chance of encountering the Shiny forms of Sentret and Gligar in the wild, and Unown U, L, T, R, and A may hatch from 10 km eggs.

Two more waves of Ultra Bonuses will follow later this month. From September 9-16, players will be able to hatch region-exclusive Pokemon such as Farfetch’d, Kangaskhan, and Taurus from 7 km eggs, and all four forms of the Mythical Pokemon Deoxys will appear in Raid Battles. The following week, from September 16-23, will see the first Gen 5 Pokemon make their debut in Go. You can see the full list of Ultra Bonuses and when they’ll be available below.

That isn’t all that’s happening right now in Pokemon Go. Niantic has also rolled out a new batch of Field Research tasks in the game. If you complete enough of them to achieve a Research Breakthrough, your reward will be an encounter with a flower-crowned Eevee, which first appeared in the game last year to celebrate the launch of Let’s Go, Pikachu and Eevee on Switch. Meanwhile, Pokemon Go’s next Community Day takes place on September 15 and features the Gen 4 starter Turtwig.
