In addition to his mythopoeic compositions, Tolkien enjoyed inventing fantasy stories to entertain his children. He wrote annual Christmas letters from Father Christmas for them, building up a series of short stories (later compiled and published as "The Father Christmas Letters"). Other works included "Mr. Bliss" and "Roverandom" (for children), and "Leaf by Niggle" (part of "Tree and Leaf"), "The Adventures of Tom Bombadil", "Smith of Wootton Major" and "Farmer Giles of Ham". "Roverandom" and "Smith of Wootton Major", like "The Hobbit", borrowed ideas from his legendarium.
