"Three Billy Goats Gruff" is adapted from a Norwegian fairytale by Peter Christen Asbjørnsen and Jørgen Moe in their Norske Folkeeventyr, first published between 1841 and 1844. It has an "eat-me-when-I'm-fatter" plot. The first version of the story in English appeared in George Webbe Dasent's translation of some of the Norske Folkeeventyr, published as Popular Tales from the Norse in 1859. The heroes of the tale are three male goats who need to outsmart a ravenous troll to cross the bridge to their feeding ground.
