The answers to riddles proposed by Gollum and Bilbo, including the first riddle said by Gollum after the game, are these: 1st - a mountain, 2nd - teeth, 3rd - wind, 4th - eggs, 5th - time, and 6th - The One Ring.

This is all I have for now on The Hobbit: An Unexpected Journey. More may be added in the future.
