Our heroine and her loyal companion, Twig.

"Plain smart and moving. John Stanley's Little Lulu meets Miyazaki."

Hilda is a series of graphic novels by British cartoonist Luke Pearson and published by Nobrow Press under their children's imprint, Flying Eye Books.

All of the books revolve around the eponymous Hilda, a bright, adventurous young girl living out in the mountainous wilderness with her mom and deer-fox buddy, Twig.

So far, the series consists of:

  • Hildafolk (originally published in 2010, and then reprinted in 2015 as Hilda and the Troll. Contains 2 stories)
  • Hilda and the Midnight Giant (published in 2012)
  • Hilda and the Bird Parade (published in 2012)
  • Hilda and the Black Hound (published in 2014)
  • Hilda and the Stone Forest (published on September 1, 2016)
  • Hilda and the Mountain King (published on September 3, 2019. Some people got early access to it.)

The series as a whole is noteworthy of being quite the audience and critic-favorite, praising its visuals and characters, particularly Hilda herself. The second and fourth books are noteworthy for being nominated and winning literature awards from the likes of British Comic Awards and the fourth book itself won the Dwayne McDuffie Award for Kids' Comics in the year 2015.


Netflix announced on June 2016 that an animated series based on the books was coming in 2018 from Silvergate Media and Mercury Filmworks and released it on September 21, 2018. A second season was confirmed during the show's panel at New York ComicCon a few weeks later, and released in December of 2020, while a movie based on the sixth and final novel was released in December of 2021. Follow updates on the Netflix show here.

The Netflix animated series has its own page.


The Hilda series contains examples of these tropes:

    open/close all folders 

    Tropes specific to the series in general 
  • Art Evolution: A weird case. The tone, look, and feel of the series is consistent throughout the books, but the differences in character appearances is very noticeable. Notice how Hilda, her mum, and Twig visually change in the first three books. However, the designs start appearing more consistent starting with The Bird Parade.
  • Black Bead Eyes: David has these eyes.
  • Character Name and the Noun Phrase: Averted at first when the first book was titled Hildafolk, but starting with the Midnight Giant, this was played straight. (Eventually, Hildafolk got republished as Hilda and the Troll to retain consistency with the rest.)
  • Cheerful Child: Hilda herself.
  • Citadel City: Trolberg is surrounded by a huge wall that was built to keep the Trolls from entering the city. The wall also has giant bell towers on top for the same purpose as well.
  • Cool Pet: Hilda's deerfox, Twig.
  • Disappeared Dad: Hilda doesn't really seem to have a father, with neither her nor her mother mentioning him. The only time she expresses interest in having a father is after being transformed into a Troll in The Mountain King.
  • Free-Range Children: Hilda and her friends often roam wherever they want to.
  • Minorly Mentioned Myths and Monsters: Almost every creature seen in the comic and series are based on Scandinavian folklore, which is little known outside of the Nordic countries.
  • Mix-and-Match Critter: Twig is a creature called a deerfox.
  • Nice Hat: Hilda consistently wears a cute French beret.
  • Nice Shoes: Hilda is almost never seen without her big red boots
  • No Name Given: We never learn Hilda's mum's name at any given point in the comics. The Netflix series says her name is Johanna.
  • Norse by Norsewest: Trolberg is implied to be somewhere in Scandinavia. Word of God confirms that the comic is heavily inspired by one of the Pearsons' family holidays to Norway, as well as the works of Tove Jansson.
  • Overprotective Mom: Hilda's mum. Can't really blame her though, considering how weird the world they live in can get.
  • Plucky Girl: Hilda in spades.
  • Scout-Out: Hilda, David, and Frida are all members of the Sparrow Scouts.
  • World of Weirdness: Hilda's whole world is filled with various supernatural creatures running about. Some of them tend to show up in Trolberg. Such as the Great Raven, and the gigantic Black Hound.

    Hildafolk / Hilda and the Troll 
  • All Trolls Are Different: Around here, trolls look like giant rocks.
  • Bait-and-Switch: Just as it seems that the troll is going to eat Hilda, it turns out that it wanted to give her back her notebook.
  • Bookends: The book begins and ends with Hilda at peace in her tent during a rainy night.
  • Early Installment Weirdness: In the original release of Hildafolk, Twig had blue fur. This was recolored to white in the paperback rerelease. The Wood Man’s house also looks different in this story, being a wooden building standing in a clearing rather than a Arboreal Abode.
  • Follow Your Nose: Hilda and Twig find the Wood Man’s house by following the smell of the smoke from his fireplace.
  • Ironic Echo Cut: A variation of this occurs when Hilda and Twig encounter a Giant walking by.
    Hilda: A giant! I bet he knows where he's going.
    (cut to the giant's POV which shows him reading a map)
    Giant: Damn it! (looks behind him) Everything looks the same from up here...
  • Orwellian Retcon: When it was first published, Twig was drawn with blue fur and a white underbelly, which was kept in the hardcover release of Hilda and the Troll. However, in the later paperback editions of Hilda and the Troll, Twig was recolored as white with little black spots on his back to retain consistency with the other books.
  • Pun-Based Title: The original title seems to be a play on Huldufólk - 'hidden people' in Icelandic.
  • Unwitting Instigator of Doom: Hilda herself when it turns out that the ringing of the bell that she put on the troll is actually considered the worst kind of torture to trolls.

    The Midnight Giant 
  • All There in the Manual: The final two pages of the graphic novel contain an overview of 20 giants, including their names and a brief history.
  • An Ice Person: Among the 20 giants listed in the final pages are at least two that are made of ice and snow: The Ice Man, and Kald the winterbringer.
  • Arboreal Abode: Wood Man lives in a house that is build around, and partly inside, a hollow tree.
  • Attack of the 50-Foot Whatever: Actually subverted with the Midnight Giant itself. It's more of a "conversation with a fifty foot whatever" than anything really. He even has a proper name: Jorgen.
  • Big Little Brother: The giant Kald was many times larger than his older brother Drib.
  • Bittersweet Ending: The Midnight Giant and his girlfriend are reunited. But in their joy, they are blissfully unaware that they crushed Hilda and her mum's house, forcing them to relocate. However, Hilda brings back the idea of moving to the city, citing how it's not so quiet in the outside anymore.
  • Brick Joke: When Hilda confronts the Mayor of the Hidden People, his fat cat sneaks into Hilda's hair. After Hilda uses this to her advantage to find out where the Prime Minister is, the cat ends up all skinny. Much later, when Hilda feels itchy and thinks she has nits, it turns out the cat gave birth to kittens (or nittens).
  • Colossus Climb: Hilda climbs on Jorgen with help of a Woff so she can talk with him. Later, the mountain she climbed to get to the Elf King also turns out to be a giant.
  • Dark Is Not Evil: Among the giants listed on the final pages is Myrkr; a giant that looks like a big shadow with eyes. According to his bio, he was associated with ill health and bad omens, but was actually terribly nice.
  • Gentle Giant: The eponymous Midnight Giant, as it turns out.
  • Invisible to Normals: The elves and their houses. Evidently, you can see them just fine as long as you fill out the proper paperwork.
  • Meaningful Echo: After the house gets attacked by invisble elves, Hilda's mum tries to tell Hilda some of the perks of moving to the city. Much later on, when everything is said and done and their house gets crushed, Hilda uses the same perks that her mum used regarding moving to the city.
  • Puppy-Dog Eyes: Hilda uses these on her mum after she brings up the suggestion that they'll have to move.
  • The Reveal: The nearby mountain turns out to actually be not just a giant, but the Midnight Giant's girlfriend.
  • "Shaggy Dog" Story: After everything Hilda did to get back on good terms with the Elves and thus be allowed to stay, it’s all rendered useless when her house is destroyed and she has to move anyway.
  • You Can't Go Home Again: Mostly because your house accidentally got crushed by giants.
  • Youthful Freckles: Hilda has these, but they don't appear in any of the later books...nor were they there in the first book.

    The Bird Parade 
  • Bad People Abuse Animals: The four kids that invite Hilda to hang out with them eventually resort to throwing rocks at birds, tipping Hilda off that they are bullies.
  • Big Shadow, Little Creature: Hilda, Raven and a Salt Lion are spooked by a monstrous shadow of what looks like the Rat King, but it’s actually just 3 white mice.
  • Easy Amnesia: A rock to the head is all it takes to make the Great Raven forget everything about who he is, his powers, and how to fly. And seeing a news paper article about the Bird Parade is all it takes to restore his memories.
  • Horrifying the Horror: The Salt Lion that attacks Hilda and the Raven backs off in fear when it spots a shadow that looks like The Rat King.
  • Identity Amnesia: After getting hit by a rock and falling, the raven Hilda befriends can't remember who he is. Not only that, but he also forgets how to fly.
  • The Moving Experience: A variation of this trope is in play when the plot has Hilda, her mom, and Twig adjusting to moving into their new home at Trolberg after their first house got wrecked in The Midnight Giant.
  • No Name Given: None of the four kids Hilda hangs out with are given a name in the story. The animated adaptation only names their leader: Trevor.
  • Suddenly Shouting: Hilda's mom when Hilda gets a little too inquisitive about why she can't explore Trolberg with the same freedom as the outdoors. She immediately apologizes for it though.
    Mum: You're not going anywhere.
    Hilda: But WHY?
  • Tempting Fate: During his nervous breakdown, the raven insists that he be left for the cats. When Hilda leaves him, a bunch of cats are nearby, ready to pounce on him.
  • Toothy Bird: Hilda's raven friend has teeth.

    The Black Hound 
  • Dangerous Forbidden Technique: Entering the Nowhere Space of the outside world, due to it’s immense size. The two Tontu’s are forced to do it anyway to avoid the car they, Johanna, Hilda and Jellybean are in from crashing into the city wall.
  • Fluffy the Terrible: The Black called Jellybean.
  • Getting Eaten Is Harmless: The Black Hound eats 3 people, but when he barfs them up again they are no worse for the wear.
  • Militaries Are Useless: The Safety Patrol is unable to track down the hound, and when they finally do they can’t capture him since their net guns are too small.
  • Our Gnomes Are Weirder: Literally so, since the nisse (Scandinavian gnome) are far more diverse creatures in Trolberg than they are in traditional folklore.
  • Pocket Dimension: Nisse live in one called Nowhere Space, made up of all the unused space in a house.
  • Scout-Out: The Sparrow Scouts.
  • Signs of Disrepair: The sign "Scout Hall" on top of Sparrow Scout HQ is missing the "T", "A" and last "L".
  • Stopped Reading Too Soon: Determined to get at least one badge, Hilda browses through the badge guide, settles on the Friend to Animals badge, and goes through the three tasks needed to earn it. Only after she finished the last task does she read the footnote that states at least one of the tasks needs to be performed in the presence of a Scout Leader in order to qualify for the badge. Cue an Oh, Crap! expression.
  • Tempting Fate: When trying to earn a badge by finding a number of locations on a map, Hilda remarks it can’t be too hard since it’s not that big a map. When she is finally done unfolding it however, the map takes up a huge section of the floor in Scout Hall.
  • Wham Line:

    The Stone Forest 
  • Adaptation Expansion: The entirety of the Stone Forest storyline was adapted for the entirety of season 2 of the animated series, with foreshadowing events of people questioning about the troll fires on the mountain. Some of the adventures from Hilda's adventure montage in the book are adapted into new stories of the season. The storyline continues into the upcoming 70-minute movie special, which is an adaptation of "The Mountain King".
  • All Animals Are Dogs: The creature that looks like a patch of land with legs act just likes a dog.
  • All Trolls Are Different: This story shows that Trolls come in a much greater variety of shapes and sizes than the ones we saw so far in previous stories. The main antagonist is a two-headed troll.
  • Baleful Polymorph: The comic ends with Hilda transformed into a Troll, and Baba herself was turned into a human.
  • Be Careful What You Wish For: Longing for absolute freedom after her confrontation with her mother, Hilda wished that she was a Troll. Unfortunately, this is ultimately what happened to Hilda by the end of the story.
  • Call-Back: Hilda's mum reuses the "Because I Said So" card on Hilda in this story after previously using it in The Bird Parade.
  • Darker and Edgier: The overall story is more somber in tone. With the relationship between Hilda and her mother becoming strained, and both of them worried about if they'll even survive their journey through the Stone Forest. Not to mention the cliffhanger at the end.
  • Disapproving Look: A "precious stone" vendor gives one to Hilda when she just grabs a rock from the ground.
  • Door Slam of Rage: When Hilda is told by her mother that she is grounded, she leaves the table in tearful anger and slams her bedroom door offscreen, much to Johanna’s frustration.
  • Enemy Civil War: Trolls don’t always get along and are shown to fight each other several times. In particular the two-headed troll.
  • Enemy Mine: It is strongly implied the mother troll mainly helps Hilda and Johanna since she too hates the Two-Headed Troll that was chasing them.
  • Go to Your Room!: Johanna says this to Hilda after the latter throws a tantrum over not being allowed to go to Frida's house.
  • Good-Times Montage: Early in the story, there 3 pages showing Hilda going on various adventures without her mom knowing.
  • Horrifying the Horror: The rock-chewing slugs terrify even the dreaded two-headed troll. And that goes double for the gigantic slug.
  • Inertia Is a Cruel Mistress: The Two-Headed Troll is finally stopped for good when Hilda and Johanna reach the exit of the caves, and the troll is going too fast to stop before he too runs outside, where the sun instantly petrifies him.
  • Not Even Bothering with an Excuse: At the beginning of the book, Hilda is seen going on so many adventures that eventually she can't think of any more excuses. One evening when she comes home covered in slime, she just tells her mum: "Whatever you're thinking, it's not that".
  • Shout-Out: There's a train in this page that distinctly looks like an inanimate version of Thomas & Friends.
  • So Much for Stealth: Zig-zagged, for laughs. When trying to escape the cave of the two-headed troll, Johanna accidentally knocks down a shelf, but the noise fails to wake up the sleeping troll. Then he wakes up when a bird he keeps in a cage starts whistling.
  • Teleporter Accident: The plot is kicked off by Johanna interrupting Hilda and Twig entering Nowhere Space, which results in all of them ending up within the titular forest.
  • Tomboyish Ponytail: Hilda sports one in this story.
  • The Stinger: After the main events of the story, Hilda's mum discovers that Hilda has been replaced with a changeling when she tries to wake her up in the morning. Meanwhile, Hilda wakes up to discover that for some reason she's in a troll cave and has been transformed into a troll child.
  • You Are Grounded!: Played for Drama when Hilda's mum grounds Hilda for A) having one too many unsupervised adventures and B) her hurtful outburst.

     The Mountain King 
  • Actually, I Am Him: At the climax of the story, Hilda finds out that Trundle was the Mountain King himself.
  • And I Must Scream: As Hilda exits the stone forest during the day, she was immediately turned to stone. When Hilda awoke at nighttime, she was in a state of panic.
  • Attack of the 50-Foot Whatever: Trundle and his brother are the two largest Trolls seen so far, with Trundle towering even over the walls of Trolberg. Trundle’s plan involves awakening an even larger Troll, Amma, who is sleeping underneath Trolberg and can destroy the whole city should she decide to rise up from her slumber.
  • Awakening the Sleeping Giant: Trundle's ultimate goal is to gather all of the Trolls to invade Trolberg. From there, the citizens will try to attack the Trolls to defend the city. This would cause the ancient Troll, Amma to awaken and protect the Trolls. But if Amma wakes up from her slumber, all of Trolberg will be destroyed.
  • BFG: The Safety Patrol's latest weapon in the war against Trolls is a gigantic cannon version of their regular torch guns.
  • Big Damn Reunion: After defeating the giant Troll that was thought to be the Mountain King, Hilda was finally reunited with her mother. In which, they both gave each other a great big hug. After that, Hilda gathered her Mother, Twig, Tontu, Baba and the giant red orb, and took them to Trundle's cave in order to undo the changeling spell.
  • Blue-and-Orange Morality: While trolls and humans have a surprising lot in common there are a few differences, Trolls believe anything not kept in a hoard means its unwanted, this includes crops and pinned animals, cause as they see it if you wanted it, it would be hidden away and guarded. The Troll mother also assumes that anything humans do is because they want to, and saw nothing wrong with using the changeling spell until Hilda called her out for doing so.
  • Cerebus Retcon: Remember in Hilda and the Troll where they showed that Trolls don't like bells being hung on their noses? Well, it was revealed that the sounds of the bells ringing causes the Trolls to go through extreme levels of pain. Hilda learned this the hard way.
  • Changeling Tale: Tontu deduces Hilda and Baba are the victim of a changeling spell. Breaking the spell drives the plot for the first half of the story.
  • Covers Always Lie: The cover of the comic prominently features the silhouette of the giant, hunchbacked troll that Hilda encounters when she goes to retrieve the giant red orb, suggesting that he is the Mountain King.He isn't; Trundle is the Mountain King, and this troll is actually Trundle's brother who is trying to prevent Trundle's return.
  • Curse Escape Clause: The changeling spell can be reversed by returning both children to their real mothers, though the protagonists only discover this by accident.
  • Cute Monster Girl: Despite being turned into a Troll, Hilda still resembles the adorable young adventurer we all know.
  • Cyclops: Trundle is revealed to be one after he regains his eye.
  • Darker and Edgier: While the overall tone isn't as dark as the previous story, but it's still quite serious throughout. With Hilda so desperate to be turned back into a human, she makes a deal with a mysterious Troll named Trundle. Also, Hilda's mother is in a situation where she needs to find her daughter before the Trolberg Safety Patrol plan a full scale war with the Trolls.
  • Deal with the Devil: Upon meeting Trundle, Hilda makes a pact with him that if she completes three tasks, Trundle will turn her back into a human. Unfortunately for Hilda, this was just a ruse so that he will be free from his prison.
  • Doomed Hometown: Narrowly averted when Hilda realized that if the Trolberg Safety Patrol attack every single Troll, Amma will awaken and the entire city will be destroyed. Hilda managed to convince Erik Ahlberg to stop the attack when she showed him the prophecy of what will happen if every single Troll is harmed.
  • Dreaming of Things to Come: When going inside the giant red orb for the first time, Hilda receives a vision of what will happen if the Trolls attack Trolberg and are harmed by the safety patrol. Hilda later uses the orb to give Erik Ahlberg the same vision so he realizes why he must order his troops to stand down.
  • Earn Your Happy Ending: After dealing with so many perils, Hilda was happily reunited with her mother, restored to her human form, and won back her mother's trust.
  • Easily Forgiven: The Troll Mother that placed the changeling spell on Hilda in the first place. Considering that the Troll did realize what she had done was wrong and apologized for her actions, neither Hilda nor her mother hold any grudge against her.
  • Extreme Omnivore: It was shown that Trolls are willing to eat almost anything. One panel had one Troll try to eat a single Woff alive. Luckily, the Woff managed to escape.
  • False Friend: Trundle pretends to be Hilda's friend in need by telling her that if she helps him, Trundle will turn Hilda back into a human. But Trundle only did this so that he can be released from his prison.
  • For Want of a Nail: Had Hilda not decided to sneak out in the previous story, not only she wouldn't have been turned into a Troll, Trundle would never have been released from his prison, and all of the Trolls would never have been reunited with Amma. Also, the Trolberg Safety Patrol would have exterminated nearly every single Troll.
  • Forgiven, but Not Forgotten: Implied with Hilda and Trundle's brother. While Hilda did apologize for attacking him when she thought that he was going to hurt her mother, the Troll's only response was a slight grumble.
  • Giant Eye of Doom: The giant red orb that Hilda was tasked to find was actually Trundle's eye. Those who enter the eye witness a prophecy of the Trolls invading Trolberg. Ultimately leading to Amma's awakening.
  • Grand Finale: The last book of the graphic novel series. However, Luke Pearson has plans to continue the animated adaptation of the series for one more season.
  • Heroic BSoD: When Baba's mom told Hilda that she doesn't know how to reverse the changeling spell, she does not take it well.
  • Impossible Task: The second task that Trundle gives to Hilda was to remove the giant bells from the entrance to his cave. The problem is that if Hilda tries to remove them, the vibrations from the bells will cause great harm to both Hilda and Trundle. However, Hilda later discovers a treasure room full of pillows. Which she uses to stuff the giant bells with so that they won't cause any noise.
  • Irony: The Troll Mother told Hilda that she has no idea how to reverse the changeling spell. In actuality, the Troll Mother is one of two components needed to help break the spell.
  • It's All My Fault: Hilda blames herself for freeing Trundle from his prison.
  • Let's Meet the Meat: At the Troll breakfast, Hilda requests a meal that is vegetarian. She is given a sentient talking carrot, who gives Hilda permission to eat his leaf.
  • Militaries Are Useless: Played straight when Erik Ahlberg tries to fight off Trundle’s brother with his torch, which is too small to harm the giant troll. Averted however during the battle for Trolberg, where the Trolberg Safety Patrol is well capable of fighting off the Trolls and their new weapon actually kills Trundle. This is not a good thing however since them hurting the Trolls is what threatens to wake up Amma.
  • Morphic Resonance: Even in their transformed states, Hilda and Baba still strongly resemble their old selves; Troll Hilda is essentially human Hilda with a grey, stone-like skin, a longer nose, bigger feet, and troll teeth, while human Baba is troll baba with human skin, but still bald.
  • My God, What Have I Done?: The Troll Mother has this reaction when she realizes that using the changeling spell on Hilda was wrong.
  • Not Quite Back to Normal: While Hilda was indeed restored to her human form, she's somehow still able to communicate with the trolls.
  • Non-Humans Lack Attributes: Trolls go about naked, but lack human "naughty bits". This means that Hilda's nudity in troll form doesn't become a problem until she is changed back to a human.
  • Posthumous Villain Victory: A variation happens with Trundle/The Mountain King as their ultimate goal is to awaken Amma, the mother of all trolls (himself included), from her slumber beneath Trolberg to reunite her with all her children and doesn't mind dying to make her awaken faster so she'll defend her attacking troll children whom he directed to attack the city in the first place. Despite all that happens Amma ultimately does reunite with the trolls, but rather than after the trolls and humans fight it instead happens because Hilda helps stop the fighting by convincing Erik Ahlberg and the Safety Patrol to stand down and let the trolls get inside the city peacefully, letting Amma communicate with them telepathically and subsequently reuniting with her once a year within Trolberg without conflict with humans.
  • Power High: Hilda quite enjoys the new powers that come with being a troll, like her great strength, stamina, and being able to roar.
  • Previously on…: The story starts off with a quick recap of the events of Hilda and the Stone Forest.
  • Ray Gun: The Safety Patrol officers have guns called torches, which fire a ray that, on Trolls, has the same effect as sunlight.
  • Red Herring: The giant Troll that Hilda faced in the Stone Forest was thought to be the Mountain King. It turns out later that he was the Mountain King's brother.
  • Rule of Three: This happened within the story three times itself:
    • Hilda's deal with Trundle to have him turn her back into a human involves three tasks. 1. Giving him a drink called Troll-mead. 2. Remove the bells from the cave he dwells in. 3. Retrieving a giant red orb from the abandoned castle of the Mountain King.
    • Hilda visited Trundle three times. The first was when she stumbled upon Trundle's cave when she was trying to hide from the Troll Mother. The second was when Hilda came back to give Trundle a cup of Troll-mead. The third was when Hilda removed the giant bells surrounding Trundle's cave, and asking him about the final task.
    • Hilda's Mother had three attempts to find her daughter. Her first attempt failed when Erik Ahlberg told her to leave the vicinity due to large activity of Trolls there. Her second try was going to the Stone Forest herself, but the opening to the forest was closed off, and was chased off by rampaging Trolls. Her final attempt was far more successful, as Hilda herself exited the Stone Forest when she was being chased by a giant Troll.
  • Scenery Censor: Once Hilda was transformed back into a human, she was unfortunately in her "Birthday Suit". Luckily, She was hiding behind a large boulder. So, the only things we see of Hilda were her arms and head.
  • Shapeshifting Excludes Clothing: Zig-zagged. When Baba was turned into a human, she also gained some clothes, but when Hilda is transformed back from a troll to a human, she is naked, while Baba retains her clothes even as a troll. Fortunately, Tontu was prepared for this and brought Hilda a set of spare clothes.
  • Spanner in the Works: Had Trundle not given Hilda the task of retrieving the mysterious red orb from the Mountain King's castle, Hilda would never have been reunited with her mother. Which in turn led to the Troll Mother being reunited with Baba. Thus, the changeling spell would never have been broken.
  • Suddenly Speaking: Since Hilda is a Troll in this story, the Trolls actually get dialogue instead of just their usual roars and grunts.
  • Super Strength: Hilda demonstrates that, even as children, Trolls are quite strong when she manages to lift and chuck a boulder several times larger than her and later she manages to carry her mother, the Troll she was swapped with, Twig, Tontu, and the red orb all at once.
  • Tailor-Made Prison: Trundle is locked in a giant cave with dozens of bells hanging at the entrance, meaning he can’t leave without setting them off.
  • Time Skip: The epilogue takes place roughly a year after the Trolls were reunited with Amma. The citizens of Trolberg declared that once a year, the Trolls will be allowed to enter the city in a event called "The Night of the Trolls". Also, Baba comes by Hilda's house to spend time with Hilda and her mother.
  • Thanatos Gambit: Trundle is counting on Amma rising to defend her troll children from being slaughtered; he goes smiling to his own death in the assumption that Trolberg and its inhabitants will soon follow.
  • Treasure Room: All trolls like to collect treasures in their caves, but have rather broad definitions of what they consider treasure. The palace of the Mountain King contains the most straightforward example, filled with gold and jewels, but Hilda also sees treasure rooms filled with car parts, pillows and other junk. Hilda grabs the pillows from said treasure room to stuff the giant bells from Trundle's cave.
  • Truly Single Parent: Apparently, most Trolls normally just have one parental figure. When Hilda asked if she had a "Troll-Daddy", the Troll Mother stated that Trolls aren't born the same way humans are. The Troll Mother also said that she found Baba when the child troll suddenly appeared to her one day, and declared Baba as her own.
  • Unwitting Pawn: Hilda was this to Trundle.
  • Villainous Plan Inertia: Trundle is killed just after smashing the walls of Trolberg, but the other trolls can now freely enter the city, and if the Safety Patrol fights back, this will provoke Amma into rising up from the ground and leveling Trolberg, just like Trundle intended. Hilda has to convince the Safety Patrol to stand down to prevent this.
  • Walking Spoiler: It's hard to talk about Trundle without revealing who he really is, why he was in that cave in the first place, and his master plan.
  • Wild Child: Baba is shown to be rather destructive due to not having any knowledge of the human world. Hilda's mother had a hard time trying to tame her.
  • Well-Intentioned Extremist: Erik Ahlberg, who really wants to defend all inhabitants of Trolberg against trolls, but this makes him prone to Fantastic Racism and rushing to conclusions.
  • A Wolf in Sheep's Clothing: Trundle, who acts like a gentle giant towards Hilda so she will accept his help in return for completing three tasks and freeing him from his prison, but this is all an act. He is actually the Mountain King, and wants to wage war against Trolberg.
