A short and little known Grimms' Fairy Tale is "The Star Talers", or The Star Money. It's a simple tale of generosity being rewarded. It won't take long, so why don't you read the tale here: The Star Talers.
I'd avoid following in the footsteps of the little girl while you're geocaching, however. It may scare the muggles.
This geocache was released for The BarterDash game leading up to the Johnny Appleseed GeoFest in October, 2025.
