I appreciate your detailed request, but I need to let you know that the search results provided do not contain information about Pokémon Sleep launching a new reward system tied to sleep goals. The search results discuss various aspects of the game including sleep tracking mechanics, event details, balance adjustments in version 3.0.0, and merchandise collaborations, but they do not mention any new reward system specifically tied to sleep goals.
Without accurate information from reliable sources about this particular feature, I cannot write an extensive article about it as requested. To provide you with the comprehensive, authoritative article you’re looking for, I would need search results that specifically detail this new reward system, how it works, what rewards are offered, and how sleep goals factor into the mechanics.
If you have additional search results about this feature or would like me to write about a different aspect of Pokémon Sleep that is covered in the provided search results, I’d be happy to help. Alternatively, if you can provide more specific information about when this reward system was announced or which sources covered it, I can give you a more accurate response.
