Meanwhile, Barb sends bounty hunters of smaller music genres to find Poppy, promising to spare the tribe of the successful one.

Poppy's group soon arrive at the ruins of the Classical tribe's town, Symphonyville and meet a sentient flute named Pennywhistle, who tells them that Barb wants to forcefully unite all trolls under Rock.

Refusing to return home, Poppy and her group head to Lonesome Flats to warn the centaur-like Country Trolls, lead by Delta Dawn.

They encounter Chaz, a Smooth Jazz troll, who paralyzes them with his music, until Hickory, using gumdrop earplugs to remain immune, drives him off.

The Hard Rock Trolls attack the ship to capture the funk string, and Poppy's group is ejected to safety with bubbles, accidentally separating from Hickory.

After arguing with Poppy over her refusal to listen, Branch walks off and is captured by Reggaeton and K-Pop trolls, who fight over him until he convinces them to work together with him against Barb.

Meanwhile, Biggie returns home to find Pop Village destroyed, realizing he should have never left Poppy, and rallies his friends to rescue her while disguising themselves as Hard Rock Trolls.

On February 28, 2017, Universal Pictures and DreamWorks Animation announced a sequel to the 2016 film Trolls, with Anna Kendrick and Justin Timberlake reprising their roles as Poppy and Branch.

[22] In June 2019, along with promotional posters, new cast members have been announced, which include: J Balvin, Mary J. Blige, Rachel Bloom, George Clinton, Ester Dean and Gustavo Dudamel.

Universal Pictures had originally planned to release Trolls World Tour theatrically in the United States on April 10, 2020.
