This story was split over three episodes, with multiple new stories in between, for the animated series.
Adaptational Early Appearance: In the graphic novels, Hilda joins the Sparrow Scouts and meets David and Frida in Hilda and the Black Hound. However, this contradicts "The Lost Clan", which contains an animated series-exclusive story in which Hilda, David, and Frida succeed in gathering a Blue Nettle for their botany badge. Adaptation Induced Plothole: The last two episodes of Season 1, which adapt Hilda and the Black Hound, keep the subplot about Hilda failing to get any Sparrow Scout badges. His role in the graphic novel is collectively assumed by Frida, David, and Gerda. In Season 2, the season-wide absence of the Great Raven effectively removes him from the adaptation of The Stone Forest. A minor elf character named Tomas appeared in the graphic novel version of The Midnight Giant, but his role was given to Alfur in the cartoon and novelizations. A Time Passes Montage early on in The Stone Forest shows single panels of various implied adventures Hilda has, some of which serve the basis for entire episodes in the adaptation. Season 2, the season finale is adapted from Hilda and the Stone Forest, and a few scenes from that graphic novel (like Hilda getting grounded) are incorporated into other episodes of the season, but otherwise the season is entirely filled with new stories. The episodes in-between are newly written stories. For season 1, episodes 1 and 2 are based on Hilda and the Troll and (mostly) The Midnight Giant, episode 3 is based on The Bird Parade, and episodes 12 and 13 (plus Hilda's Sparrow Scout initiation at the start of episode 4) are based on The Black Hound. Ostenfeld's flat, there is a cuddly toy of Humpty, one of the toys from Play School, sitting on the sofa. Ostenfeld, who is voiced by Play School legend Derek Griffiths.
Actor Allusion: In "The Fifty Year Night", Hilda investigates a mystery involving her neighbor Mr.She does apologize to them in "The Black Hound", though said apology is about her hanging out with the Marra more than their initial fight, which is resolved largely offscreen.
While it does lead to bouts of significant character development, the aftermath of Frida's falling out with Hilda and David in "The Ghost" is mostly pushed to the sidelines.Hilda attempting to find anything that could potentially discredit Erik Ahlberg is set up to be a recurring plot thread throughout Season 2, but after a failed attempt in "The Draugen" and a brief mention in "The Witch", it's never brought up again.2D Visuals, 3D Effects: Played straight as of Season 2.
