The Surprise Record is an item that falls under the category of "Music" in the Supplies. It is a piece of music composed by Haydn. It is known to be one of the records that evoke nature, and that in a certain part of the song, it can scare your dogs. This lowers the player's Trainer Points/Owner Points. It can be found on walks and sells for $9 at the Secondhand Shop. Your dogs will fall asleep, and at some point, will wake up abruptly.
DS: "Composed by Haydn, this is one of six mystical records that evoke nature."
