The background of this article is set after The Hobbit 3. The "greedy and evil" dragon Smaug did not die, but was injured by the dwarves and turned into a young dragon state. Thranduil was unhappy because Little Leaf ran away from home and returned to his nest in the jungle, where he met our dragon treasure.
Smaug (his eyes sparkled when he saw the golden Thranduil) "I am the owner of the Lonely Mountain gold mine, my wife. Can I buy the entire Middle-earth and give it to you?"
Thranduil: "This little thing looks a bit similar to Ye Zi when he was a child. Keep him to relieve his boredom first."
