Emily was a piece of granite that formed part of Millie Mountain until Frazzella Frost caused her to tumble down the mountain and into the river below. Emily broke apart into smaller pieces as she was tumbled down the mountain and floated in the river. Eventually, gusts of wind blew what was left of Emily, now the size of a sand grain, into a sand dune called Sam where she and the other sand grains cemented together to form sandstone.
