New Event - Ash Pikachu
On March 31, 2019, Niantic released what is speculated to be an April Fools feature: Ash Ketchum from the Pokemon anime can photobomb your Pokemon in GO Snapshot!
After the photobomb is done, you have a chance to catch Ash Hat Pikachu. It can be shiny as well.
This is only available during April Fools Day, which is happening in Australia first.
Stay tuned for the full announcement, which is expected to drop April 1st.
