(Part one of the Rocking Harmony AU) John Dory found himself on Vacay Island after he spotted some Techno Trolls setting up for a rave and couldn't pass up the opportunity. After a very close encounter with the Rock Trolls and learning that they are after the six musical strings and the members of BroZone to use the Perfect Family Harmony to unify the six tribes under rock, he and Bruce race to gather the rest of their brothers and hopefully protect the strings along the way.

(Direct sequel to Trolls Rocking Harmony and prequel to Trollstopia: True Harmony) Shortly after the concert held on Vacay Island, Poppy and Viva decided to hold a sort of gift-exchange event to help the tribes mingle more. TIny Diamond goes on a journey to get his flow back. Branch enlists the help of Floyd, Prince D and Cooper to make the perfect gift. Clay and Viva go to different members of Kismet and the Snack pack for advice. John Dory and Bruce try to figure out how to pick out a gift for a troll that they only got to know again less than a week or two ago.

(This is part three of the Rocking Harmony AU, taking place after The Intertribal Gift Exchange) Poppy, Branch, Clay and Viva have finally completed the plans for the new wonderful city named Trollstopia. The Pop Queen invites each tribe to send over an ambassador to check out what Pop Village and this new city has to offer. This is the daily life of Poppy and Co as they build and expand on Trollstopia, with the cultures of the tribes mingling together while at the same time reintegrating the Putt-Putt Trolls into Pop Troll society.
