Pokémon Sleep’s October New Moon event gives Mew and Darkrai special encounters
New Moon Day runs October 10–13 across Pokémon Sleep’s areas, with special Mew and Darkrai encounter chances during the first daily sleep research.

Before we dive in
Pokémon Sleep is a mobile game that turns recorded sleep into Pokémon research. After a sleep session, players discover visiting Pokémon and offer snacks to build friendship; becoming full can stop a Pokémon from accepting more snacks.
A special encounter rate creates an opportunity, not a guaranteed visit. Mew and Darkrai are Mythical Pokémon, making this event about unusual research encounters rather than a new game mode.
The update
A previously announced weekend event is almost here. Pokémon Sleep’s October New Moon Day puts Mew and Darkrai on the research possibilities list.
The event runs October 10 at 4:00 a.m. through October 13 at 3:59 a.m. in all areas. Mew and Darkrai can appear regardless of sleep type. During the first snack time, Pokémon are less likely to become full.
Only one special-rate Pokémon can appear during the first research of a day; none appear during the second. Encounters remain uncertain, and chances rise slightly after misses. Each special encounter adds three friendship points. Event days roll over at 4:00 a.m.
