The Holiday 2025 Double Dream Shard Research event in Pokémon Sleep will run from December 22 to 29, giving players a full week to rack up extra Dream Shards through boosted research rewards. To go along with the event, Togedemaru, Cetoddle and Cetitan will be added to the game, expanding the roster with new sleep styles to discover. It’s a nice combo for players who want to progress faster while also meeting fresh Pokémon during their nightly sessions. With bonuses and new additions landing at once, this year’s holiday event should offer plenty of incentive to check in each day.
