Quick recap
On their first date, Poppy and Branch run a gift exchange: each Troll draws another's name and buys a present. The two draw each other. Tiny Diamond drew his father, Guy Diamond, and can't find a rhyme for "Diamond"; he climbs a mountain and the cloud monks help him. Branch, panicking, builds a machine to do Poppy's hair, and it blows up. Tiny helps him look through the wreckage, and Branch finds a photo of the two of them. At the swap, Branch gives Poppy a scrapbook of their story. Her gift to him is an empty box: nothing would be good enough. The Trolls sing "Together Now."
