Niantic has announced that that April 2022 Community Day Pokémon will be Stufful. They have also announced they are reducing the time period from 6 hours to 3 hours.

April 2022 Community Day: Stufful

Saturday, April 23, 2022, from 2:00 p.m. to 5:00 p.m. local time

Trainers,
We’re excited to announce that Stufful, the Flailing Pokémon, will make its Pokémon GO debut during April’s Community Day event! Stufful will appear in the wild, and if you’re lucky, you might encounter a Shiny one!

Community Day Adjustments

We also wanted to take a moment to discuss some changes to the Community Day format we’ll be testing. In 2020, we doubled the length of our Community Day events, extending them from three hours to six. Since then, however, we’ve found that only five percent of our Trainers tend to participate in the event for more than three hours.

One of the biggest pieces of positive feedback that we received after January’s three-hour Community Day Classic was that players and community leaders noticed how much more of the community was out and about during the event. So, for Stufful Community Day, we’re returning to three-hour format. Our hope is that doing so will create even more opportunities for Trainers to play together and connect outside as they’re exploring.

We know that Trainers have enjoyed all of the extra resources that can be collected during longer events, so we’re adding some new and exciting perks to Stufful Community Day to give you the ability to collect just as many resources during gameplay. Check them out below!
