Pokémon Sleep’s latest update adds data for Misdreavus and Mismagius
Sleep’s October 22 update adds Misdreavus and Mismagius data ahead of next week’s event; availability follows the event schedule.

Before we dive in
Pokémon Sleep uses sleep tracking and helper Pokémon to support research at a campsite. An app update can add event data before the associated Pokémon are actually available to encounter.
The update
Pokémon Sleep’s October 22 update includes new data for two Ghost-type Pokémon ahead of next week’s event.
Serebii reports that the update contains data for Misdreavus and its evolution Mismagius, along with information for next week’s event.
This update report alone does not confirm that both Pokémon can already be encountered. Check the event notice and its start time before using encounter items; new data in the app is different from an event being live.
