<P> "Three Billy Goats Gruff" (Norwegian: De tre bukkene Bruse) is a Norwegian fairy tale . The fairy tale was collected 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 (Aarne - Thompson type 122E). </P> <P> The story introduces three male goats, sometimes identified as a youngster, father and grandfather, but more often described as brothers . In other adaptations, there is a baby or child goat, mama goat and papa goat . In any case, there is almost no grass left for them to eat near where they live, so they must cross a river to get to "sæter" (a meadow) or hillside on the other side of a stream in order to eat and fatten themselves up . To do so, however, they must first cross a bridge, under which lives a fearsome and hideous troll, who is so territorial that he eats anyone who tries to cross the bridge . </P>
