April has arrived, and Niantic is kicking off the month with a new event in Pokemon Go. The Tricky Pokemon event is underway for a limited time, and it introduces a new Gen 5 Pokemon to the game, as well as a couple of new Shiny forms.

Until 10 PM local time on April 7, Pokemon that specialize in mimicry–such as Voltorb, Ditto, Sudowoodo, and Foongus–will appear in the wild more often than normal. You’ll also have a chance of finding Shiny versions of Sudowoodo and Croagunk during the event.

On top of that, a new Gen 5 Pokemon, Stunfisk, has made its debut in the game; you can encounter one in the wild, as a Field Research task reward, or hatch one through 5 km eggs. Once the Tricky Pokemon event ends, Stunfisk will no longer hatch from 5 km eggs, although you’ll still have a chance of finding one in the wild or through Field Research tasks.

Finally, Niantic is offering a special set of Field Research tasks during the event, which can lead to encounters with the aforementioned Stunfisk, Sudowoodo, or Croagunk. The developer also teases that a special Pokemon may appear when you take Go Snapshots. You can read more about the event on the official Pokemon Go website.

In addition to the Tricky Pokemon event, April’s new Field Research tasks are now live in Pokemon Go. Each time you achieve a Research Breakthrough this month, you’ll earn an encounter with Alolan Exeggutor. Niantic is also extending last month’s Team Rocket Special Research quest, so you now have until the end of April to rescue Shadow Entei.

The Legendary Pokemon Landorus has also made its debut; you can encounter it in Raids or as a Go Battle League reward until April 21. To make it easier to participate in Raids during the COVID-19 pandemic, Niantic has temporarily doubled the distance from which you can interact with Gyms, and it will soon give you the option to do Raid Battles from home.
