Pokemon Go Brings Back Ash Hat Pikachu For April Fools' Day

April Fools’ Day is here, and like many other developers, Niantic is celebrating with a special event in Pokemon Go. Last year, the developer memorably replaced the game’s 3D Pokemon models with 8-bit sprites, but this year, it’s giving players another chance to capture a Pikachu wearing Ash Ketchum’s signature hat from the Pokemon anime series.

Throughout the day, you’ll be able to come across a hat-wearing Pikachu when you take pictures using the new Go Snapshot feature. Like Smeargle, the Pikachu–or even Ash himself–will potentially photobomb the pictures you take; if that happens, back out of the mode and the Pikachu will appear in the wild, giving you an opportunity to catch it.

This marks the first time in more than a year that Ash’s hat Pikachu has been available in Pokemon Go. Niantic first introduced it as part of the game’s anniversary event, although there have been numerous other hat-wearing Pikachu since, such as a Santa hat Pikachu during the game’s annual winter event.

This also marks your final chance to catch Giratina in its Altered Forme. The Legendary Gen 4 Pokemon returned to Raid Battles last week following Dialga’s departure. Starting 1 PM PT / 4 PM ET, Giratina will transform into its Origin Forme–the more serpent-like appearance it takes in Pokemon Platinum–until it leaves Raid Battles on April 29. You can find tips on how to catch Giratina here.

Niantic is also kicking off a Bug Out event on April 2, during which Bug-type Pokemon will appear more frequently and Incenses will last twice as long as normal. Following that, the developer is hosting this month’s Pokemon Go Community Day on April 13. The featured Pokemon this time will be Bagon, the base form of the popular Dragon Pokemon Salamence.
