A letter from NBCUniversal, mostly redacted 

Trolls World Tour and Rocklantia 

​Though a sequel, the premise of DreamWorks'Trolls World Tour bore more resemblance to the novel Rocklantia than to the original film Trolls. This sequel was released in 2020.

Hollywood and it's plagiaristic, meathead screenwriters will have to try harder next time to capture the awesomeness of Rocklantia as Trolls World Tour was a dud.
