Do Not Eat Trolls

20th Century Fox and Dreamworks' movie Trolls depicts how some people are trying to find an easier way to get happy by feeding off the happiness of others. As Trolls are the happiest creatures in the movie's universe where they are eaten by Bergens to gain happiness. The main character, Branch, who became the unhappiest Troll because he blames himself for the death of his grandmother. The creators used irony, hyperbole, situational humor and sarcasm to depict the unhappiness of a character and constant happiness of the other until the very end. It also aspires little children to find happiness inside of themselves rather than feeding off other people.

When Poppy's friends were kidnapped by Bergens she rushes to find Branch who is supposedly knows everything about bargains she uses hyperbole:

Poppy: Branch, we just got attacked by a Bergen.
Branch: A Bergen
Poppy: It took everybody!

Branch because of his sad and negative nature uses a lot of sarcasm and irony everytime Poppy has a positive attitude or uses hyperbole as above.

Branch: Why don't you try scrap booking them too freedom?

She gets annoyed with him and asks him if he will stay in his bunker forever. Branch replies with hyperbole:

Branch: Forever? No. Yeah, I really only have enough supplies down here to last me 10 years, 11 if I'm willing to store and drink my own sweat, which I am. You all said I was crazy, huh? Well, who's crazy now? Me, crazy prepared!

Later in the story we find out that Branch's singing was at fault of his grandmother's death. Every time Poppy starts to sing his response is:

Branch: Do you have to sing?
Poppy: I always sing when I'm in a good mood.
Branch: Do you have to be in a good mood?
Poppy: Why wouldn't I be? By this time tomorrow, I'll be with all my friends. I wonder what they're all doing right now.Branch: Probably being digested.

He uses sarcasm again to cover up his emotions. The whole movie consists of Poppy trying to force Branch to be happy and hearing sarcastic or ironic responses from Branch. Branch is the character that is supposed to be represented to be the person that find happiness inside from guidance of his friend Poppy. Bergens on other hand just straight up eat Trolls every year to stay happy. 

Then there is some adult jokes that were quite out of place such as short conversation between Branch and a minor character. Such conversations were most likely used to keep adults also interested in the movie or something to internally laugh at and ignore kid's demands of explaining the jokes.

Branch: You don't get sarcasm, do you?
Cooper: I think I had a sarcasm once.

In the end it shows two kinds of people that seek happiness from others. One kind is the one that swallows happiness of the other person to become happy like Bergens do and another kind is the one that finds happiness inside with guidance of other happy people.
