Hilda and the Mountain King (2021)

Picking up from “Chapter 13: The Stone Forest”, Hilda, now a troll, runs away from Trylla and is petrified by the sunlight when she leaves the Stone Forest. Meanwhile, in Trolberg, Johanna discovers Baba in Hilda’s place, and Tontu deduces Hilda had become the victim of a changeling spell. Realizing what this means, Johanna, Baba, Tontu, Alfur, and Twig go searching for Hilda but are unable to locate the entrance into the Stone Forest. Elsewhere, Erik Ahlberg holds a press conference in which he announces a curfew because of the increasing troll activity outside Trollberg. The students of Edmund Ahlberg Elementary School watch a safety video about trolls, but Frida and David protest the inaccurate information portrayed in the video.

Other students eventually join their protest, but David is forced to bail out when he learns his mother has joined the Safety Patrol as a volunteer bellringer. As evening approaches and with still no sign of Hilda, Johanna runs into a group of Safety Patrol officers, giving her no choice but to reluctantly return home. After sunset, Hilda unpetrifies, and finds herself unable to return to Trollberg because of the belltowers. As she retreats, Hilda stumbles upon a huge cave with dozens of bells hanging from the ceiling of the entrance. Inside, she finds a gigantic blind troll, who calls himself Trundle.
