" In a hole in the ground there lived a hobbit. Not a nasty, dirty, wet hole, filled with the ends of worms and an oozy smell, nor yet a dry, bare, sandy hole with nothing in it to sit down on or to eat; it was a hobbit-hole, and that means comfort."
Gandalf and the thirteen dwarves ask Bilbo to join the company. "Excitable little fellow" Bilbo refuses at first but then joins the company.
The company crosses the forest of the elves and run into a little trouble with orcs.
They get to Lonely Mountain where Smaug the dragon is asleep. They soon start a battle with him.
All out war at Lonely Mountain. The dwarves win. Bilbo Baggins returns home to his hobbit hole.
