One of Stardew Valley’s most intriguing aspects is the series of Secret Notes that players can discover throughout their journey. These notes contain cryptic messages and puzzles that lead to hidden areas and rewards within the game.
Secret Note 25, in particular, has been a topic of discussion among players due to its elusive nature and ambiguous meaning.
What is Secret Note 25 in Stardew Valley?

Secret note 25 is a note with a cryptic text, that reads:
I ‘borrowed’ a necklace from Mom, but lost it somewhere near the bath house… She’s going to freak out if she notices it’s missing!
Secret Note 25, Stardew Valley

You can find the necklace by fishing in the small fountain outside the bathhouse, north of the Mountain area.

Although Secret Note 25 is not signed, the note appears to have come from Abigail, as you get double the friendship points for returning the ‘borrowed’ ornate necklace to her, instead of her mother, Caroline.
Once you have the necklace, you can place it in the inventory and return it to either Abigail (for 100 friendship points) or her mother Caroline (for 50 friendship points).
If returned to Caroline, the message will appear “What’s this? My old necklace? That’s strange, I didn’t even notice it was missing… Well, thanks for bringing it back, [name].
The game is designed to automatically attempt to hand it over to any Non-Player Character (NPC) you interact with. However, only Caroline or Abigail can accept it.
If you try to give it to anyone else, the effort will fail, and you’ll see a dialogue that says “Wrong Person.” To ensure it goes to the right person, start a conversation with the person you want to give it to, as the transfer happens automatically.
You can find more about the exact chances of finding a note in each of these places in this walkthrough for Secret Note 19.
