This came out in 2021, but I didn't see it until 2024. It takes place after the second movie, as well as like the first four seasons of "TrollsTopia" (which I haven't seen). As with the last holiday special, the holiday in question is not Christmas, but is rather Christmasy. Poppy decides to create the first annual secret gift exchange, so while she and Branch are on a balloon ride, they toss out cards all over the Trolls kingdom, and everyone's card has someone else's name in it, for whom they will get a gift. Poppy and Branch get each other's names, and they both worry about what to get each other. Meanwhile, Tiny Diamond gets his father's name, and decides to write a rap song for him. But he can't think of a rhyme for one of his lyrics, so he goes on a quest to "get his flow back".

That's all I want to reveal of the plot. I thought it was fun and amusing, with a few good songs, but I don't expect to find it particularly memorable. Still, it's the kind of thing I probably wouldn't mind re-watching someday.
