Pokemon Go developer Niantic has announced another new event for the game. Starting Tuesday, April 21, the developer is holding a buddy event, which will bring out rare Pokemon and offer extra in-game bonuses for a limited time.

Throughout the event, Pokemon like Alolan Meowth, Chansey, Eevee, Feebas, Lillipup, and Joltik will appear in the wild and hatch from eggs much more often than usual. You'll also have your first chance to encounter Woobat--which was previously available as February's Research Breakthrough reward--in the wild.

Other Pokemon you'll be able to find during the event are Volbeat and Illumise. These two monsters are notable because each is normally only found in certain regions; Volbeat only appears in Europe, Asia, and Oceania, while Illumise is exclusive to the Americas and Africa. During the event, however, both Pokemon will be spawning around the world, and you'll have a chance to encounter Shiny versions of them.
