The Pokémon Go April Fools' Day 2025 event revolves around Poké Balls and Pokémon encounters.
The 'What's That Poké Ball?' event takes place only on April 1, from midnight to 11:59 p.m. local time.
During the event, in addition to regular Pokémon spawns, you will find Poké Balls on the map that can yield items or Poké Ball-imitation Pokémon.
The Spotlight Hour for April 1 features more Poké Ball spawns on the map and a 2x catch bonus, providing an opportunity to catch the featured Pokémon in higher numbers.
