It's been five years since everything was awesome and the citizens are facing a huge new threat: LEGO DUPLO® invaders from outer space, wrecking everything faster than they can rebuild.

After the monstrous Bergens invade Troll Village, Princess Poppy, the happiest Troll ever born, and overly-cautious, curmudgeonly outcast Branch set off on a journey to rescue her friends. Their mission is full of adventure and mishaps, as this mismatched duo try to tolerate each other long enough to get the job done.
