Trolls (OC insert)

Val is the only troll-sized human in the world of trolls. She doesn't remember where she's from and lives alone. One night, a colorless troll named Branch finds her and takes her in. Branch has always been like a brother to her and has always protected her. Val met all the other trolls, especially Poppy, and became good friends with them. She was also told about their enemies, the Bergens. But one day, a Bergen invades Troll Village and kidnaps some of their friends. Poppy, Branch, and Val set off on a journey to rescue their friends. The mission is full of adventure and mishaps. Will they be able to save their friends?

(I don't own the movie Trolls. I only own my OC. If you want this to be a reader insert, then use your name instead of Val. Hope you like the story.)
