Why did Smaug take over Thror's treasure {this question is from hobbit} please answer quickly

The phrase that revels setting is whisper because it shows what he is doing .

All you gotta do is write about animals and how they can relate to you, for eat, they have a family, they have a heart, they have feelings, a bird can fly and probably that can be a symbol like your dreams “sky is the limit” etc etc
