After Queen Poppy and the Trolls took away Trollstice from Bergen Town, the Bergens have no holidays to celebrate. After receiving cards from the Bergens (all of different days of the week or times of a day), Poppy comes up with an idea, to give the Bergens some of their holidays to celebrate the season. The queen enlists her friend Branch (who is new at this "happy" thing), and the Snack Pack, to travel to Bergen town by bus, driven by Cloud Guy (much to Branch's annoyance). After the trolls travel through a crazy wormhole, Poppy, Branch and the Snack Pack arrive in Bergen town, to give the Bergens some holidays to celebrate.

When the Queen of the Hard Rock Trolls tries to take over all the Troll kingdoms, Queen Poppy and her friends try different ways to save all the Trolls.
