Pokémon Sleep may expand its event structure beyond New Moon Day by introducing boosted appearance rates during Good Sleep Day events, potentially allowing players to encounter specific Mythical Pokémon tied to each event. The idea suggests a more structured rotation that gives players clearer chances to find rare Pokémon without relying entirely on standard sleep sessions. While details are still under consideration, the change would align with the game’s ongoing push to keep events engaging and reward consistent play, especially for those tracking long-term progress and aiming to complete rarer entries.
