Plot 
While going on their first date, Poppy explains to Branch that she is planning a gift exchange, with baskets filled with invitations; each one has the name of another Troll in Troll Kingdom. The Troll has to buy a secret gift for that Troll and will meet in Pop Village in three days time to exchange gifts. Poppy and Branch deliver the baskets all around the kingdom before finishing in Pop Village. When they are done, they pick out the last cards and pull out each other's names, with Poppy excited to have pulled Branch's name and Branch horrified to have pulled Poppy's. Nervously, both part ways.

At Pop Village, Tiny Diamond grabs an invitation and pulls out his father's name "Guy Diamond". He does a rap, but finds it hard to rhyme with "Diamond", believing he has lost his flow. After a few failed attempts to find the perfect rhyme, Tiny heads to the top of a mountain to seek out the monks at the Cloud Temple. When he arrived, Tiny starts to meditate with the Clouds, who helped him realize that he just had to rhyme "daddy" and has his rap sorted.

Back in Pop Village, while Trolls are already gathering and busy, Poppy finishes her touches of her gift to Branch, confident that she has it right. Meanwhile, Branch comes up with the idea for a machine that does Poppy's hair, but after getting her head measurements without her knowing, he sees her gift to him and runs back to his bunker. Panicking that his gift will not be enough, Branch goes over the top and builds his machine, adding more and more functions constantly. After he finishes, he tests out the machine and it explodes, sending him into space then back down to the village. When Tiny finds him on the ground, Branch believes he failed and tells him what happened. Tiny passes on the wisdom he just learnt and tells Branch to look through the clutter. While cleaning up the mess in his bunker, Branch finds a photo of him and Poppy and realizes what he must do.

During the gift swap, Poppy and Branch reveal they got each other's names. Branch presents Poppy with a scrapbook detailing all the events up until that day, which she finds wonderful, as it is only something he could give her. When Poppy opens her gift to Branch, it turns out to be empty, because she knew there was nothing good enough for him. Poppy and Branch hug as they realize they just need each other, and they and all the other Trolls start singing “Together Now”. As the song ends, Poppy and Branch go off on another balloon ride over Troll Kingdom, with Poppy kissing Branch on the cheek.
