Niantic is kicking off a spring celebration in Pokemon Go on April 4. The event runs for four days and features various spring-themed Pokemon, including Shiny Bunnelby and Mega Lopunny, the latter of which will be available for the first time in the game as a Mega Raid boss.

Throughout the spring event, flower crown-wearing versions of Pikachu and Chansey will appear in the wild, as will the following Pokemon:

• Exeggcute
• Marill
• Plusle
• Minun
• Bunneary
• Bunnelby

You'll also be able to find some Shiny Pokemon during the event. In addition to the aforementioned Shiny Bunnelby, you'll have a chance to catch Shiny Chansey in the wild. You may also hatch a Shiny version of Chansey's pre-evolved form, Happiny.
