Because Hilda features a diverse cast of creatures, there are multiple minor creatures that have only been seen once, often no more than a cameo, and never given a proper name in the series. They will be listed here:
In "Hildafolk", when Hilda and Twig are lost in the woods, a panel shows they are being watched by three unidentified creatures, of whom the reader only gets to see their silhoutte. They are standing around a tree that has a face.
Forest creature[]
This creature is briefly seen in "Hildafolk" when Hilda and Twig are lost in the woods, just before Hilda smells smoke from the Wood Man's house.
Birdcat[]
At the back of "Hildafolk" are some of Luke Pearsons' sketches for the Hilda series. One of them depicts this bird-cat hybrid creature, that ultimately was never used in any of the stories.
This large, white rose is seen in a single panel in "Hilda and the Stone Forest". It unleashes a green, slimelike substance onto Hilda, which Hilda later tried to explain to her mom without revealing she went on an adventure.
Book ghost[]
Early in "Hilda and the Stone Forest", a single panel shows Hilda and Frida summoning this creature from a book in the Library. Hilda was still stunned by the experience when she returned home in the next panel.
Green Worms[]
These large, green, wormlike creatures are seen in a single panel in "Hilda and the Stone Forest", on board the wreck of a ship Hilda and Twig are visiting.
Carrot Creature[]
This creature was briefly seen in "Hilda and the Mountain King", when Hilda, who had been turned into a Troll, declined the meat the other Trolls offered her and asked for something vegetarian instead. She was offered a carrot, but before she could take a bite the carrot turned out to be a living creature. Hilda thus refrained from eating it. It is theorized that it may be a Vittra, although this is unclear. A similar scene also appears in the movie.
Animated series[]
Footprint creature[]
In The Hidden People, while Hilda and Twig are running away from a Troll, they come across this giant footprint in the landscape, which puzzles and awes Hilda.
This footprint may be from Jorgen, but so far, it hasn’t been confirmed.
Flying Pigs[]
This unseen creature was mentioned by Alfur in The Lost Clan when he stated that events in which pigs gain the ability to fly occur “with some regularity”.
Ground Cows[]
These creatures are shown to live in the underground portion of Gorrill Gardens. They resemble cows, but only come up to Hilda's waist. A Vittra is shown herding them in The Sparrow Scouts, and another is seen painting one.
Moss Creature[]
This creature appears in The House in the Woods. This creature resembles a large insect, with moss growing on it’s back.
It was resting on a tree on some actual moss, but retreated when Hilda took a closer look while trying to navigate her way back to Trolberg (using the navigation technique that moss always grows on the north side of trees).
Novelization & other books[]
Snaggletooth python[]
A creature that is briefly mentioned by David in "Hilda and the White Woff", but not actually seen. It is presumably some kind of snake.
Will-o-the-wisps appear as tiny, flickering balls of light, that lure unexpected people into swamps in an attempt to drown them. If the victim escapes, the will-o-the-wisp is known to get sulky.
Hilda Creatures[]
The game Hilda Creatures features a wide variety of birds, dogs and foxes that the player can try to find.
