Pokémon Sleep Announces “Latios and the Drops of the Heart” Event
The Pokémon Company has officially announced a brand-new two-week event for Pokémon Sleep, featuring the legendary Eon Pokémon Latias and Latios.
The event, titled “Latios and the Drops of the Heart”, will run from June 8th through June 22nd, 2026, and will give players new opportunities to encounter both legendary Pokémon while working together with researchers around the world to restore the mysterious “Drops of the Heart.”
A Global Research Event
According to Professor Neroli, unusual weather conditions have been causing sleep disturbances among Pokémon across several regions. At the same time, the mysterious gem-like “Drops of the Heart”, which share a deep connection with Latias and Latios, have reportedly become clouded and lost their radiance.
Throughout the event, players will help restore the Drops of the Heart by conducting sleep research, gathering event items, and contributing to a global community goal through a special Event Sleep Power system.
As researchers around the world sleep and conduct research, Event Sleep Power will accumulate and contribute towards restoring the legendary artifacts.
Latias and Latios Take Centre Stage
Both Latias and Latios will receive boosted appearance rates during the event, making it one of the best opportunities yet to befriend the legendary duo.
Players who sleep with Latias or Latios on their team will receive a 10% Sleep Power bonus, while those who manage to have both Pokémon on the same team will receive an even larger 30% Sleep Power bonus.
The event will also introduce special event-exclusive items and rewards, including:
- Latios Incense
- Latias and Latios Candy
- Event-exclusive exchange items
- Special event research rewards
