Answer:
Thorin particularly wants the Arkenstone, a special piece of the treasure that Smaug has taken over and is guarding. Thorin also hopes to become King Under the Mountain. The rest of the dwarves want to share in the treasure. They want to go and take back Thorin's father's treasure from the dragon, Smaug. On the way, Bilbo and his companions face many hardships, including encounters with trolls, elves, goblins, and a creature called Gollum.
