Pokémon Sleep’s Meal Prep Week Vol. 1 event runs Nov. 9-16, increasing the appearance rates of Pokémon that gather ingredients and introducing a new Sleep Style Dex goal that can expand cooking pot capacity. Players who register 570 styles during the event can reach the goal, while Stufful and Trapinch will appear on Greengrass Isle and Greengrass Isle (Expert). Event bonuses include a 1.25 multiplier to dish strength, increased candy and Dream Shard rewards for researching Pokémon with the Ingredients specialty or Ingredient Draw S skill and access to Mini Candy Boost, which doubles candy EXP at four times the usual Dream Shard cost. The event is designed to help players prepare for three recipes arriving during Bountiful Banquet Week, which begins Nov. 16.
