Later, in Chapter 4, the narrator explains that Goblins are so wicked they are probably responsible for inventing the machines that have since been used in war to kill many people at once. As he is tested, Bilbo discovers his own inner strength, loyalty, and cunning.
Bilbo, for example, encounters Goblins, Wargs, elves, Gollum, and Smaug the dragon on his journey to help the dwarves retrieve their treasure, and he travels well beyond the hobbit-lands through Mirkwood and the Misty Mountains to the Lonely Mountain.
