The Pokémon Sleep “Buncha Berries Week Part 1” event, running from September 29 to October 6, will introduce Natu and Xatu for the first time in the game. This event gives players a chance to encounter these Psychic/Flying-type Pokémon while enjoying the usual sleep-related activities and bonuses. It’s a fun opportunity for Pokémon Sleep players to add these iconic birds to their Pokémon collection and earn rewards by participating in the event’s berry-focused activities.
To go along with Pokémon Sleep’s Buncha Berries Week, Berry Week Bundles Vol. 1 in sizes S, M and L will soon be available. These bundles are packed with useful items to help you make the most of the event and boost your berry-collecting efforts. Keep an eye on the in-game shop for their release and get ready to stock up.
