Found: A toy dropped by Teresa

We've been sitting on this finder note for a while, and our detective skills have finally been exhausted! Can you solve this one and let us know which drop this was?

Teresa,

We found little Sarah (that's her name now) at the park across the street from the apartments today. Thank you for making her for our little girl! She's very pretty, and we can tell that she was made with love.
