In the classic fairy tale, Hansel and Gretel are two young children who are cast outside their home by a cruel stepmother during a famine after she decides to sacrifice the siblings to save herself and their father, a woodsman. The first time she attempts to leave them in the woods, Hansel cleverly leaves white pebbles that he drops onto the forest floor, which he then uses to lead him and Gretel back home. The second time, however, the brother and sister pair aren’t quite so lucky: this time, Hansel only has bread crumbs to leave a trail, which are unsurprisingly gobbled up by birds. And so they are lost.
