This is what's written in Arthur Spiderwick's Field Guide to the Fantastical World Around You about Trolls.

Trolls (Family: Nocturnidae)Edit

Trolls are afflicted with a ravenous and never-ending hunger leading them to devour whole flocks of livestock. In particular they have a taste for sheep, but will eat whatever they can catch. Trolls can survive extreme weather conditions and therefore tend to settle as far as possible from human settlements. Nocturnal by necessity since sunlight will turn them instantly to stone, trolls are more common far to the north, where it is dark for months at a time.

Water trolls live primarily in or near freshwater and usually make their home in a makeshift nest of rushes and mud along the banks of a bog or deep river. Bridges are also good places to build beneath as they provide shade even in the winter months.
Bauer's Troll

A female Bauer's Troll (Vorax baverensis).

As soon as a troll moves into a new lake or river, it begins excavating stones and debris to keep the channels deep enough so it may move about easily. Greater depth allow safety from the sun, as trolls are able to hold their breath for hours on end

Though they appear brutish, trolls can communicate in the local tongue and are skilled at word games. There are reports of trolls carrying off captives for reasons other than hunger. One northern species, Bauer's troll, has even been recorded deceiving humans into believing it can live in accord with them. People would do well to recall trolls are malicious opportunists always on the lookout for their next meal.


Known speciesEdit

  • River Troll (Vorax flumineus)
  • Bauer's Troll (Vorax baverensis)
  • Mole Troll (Vorax Talpa)

Additional factsEdit

Trolls are in fact related to Ogres, which probably means that they also are descended from giants, but often less cunning than trolls. Nonetheless, they are extremely dangerous.

When a Water Troll is submerged, the only visible parts of his body is usually the hump and top of their head, which looks like partially water-covered rocks; the creature's long hair looks like grass.

Trolls have very long ears and big noses. Thus, they have exceptionally good senses of smell and hearing.

Trolls are quite agile in the water, but somewhat clumsy on dry land. To fix this problem, they balance their immense mass on their enormous knuckles.

Known TrollsEdit

Grendel, the beast in the epic poem Beowulf, was probably a malicious Troll with taste for human flesh. He and his mother, who was even worse, lived in a marsh close to a Danish royal castle. Every night, Grendel would walk into the castle, kill a few people, and bring them back to his home. Finally, the Scandinavian hero who gave the poem its name arrived and killed Grendel and his mother.

Theodore Spiderwick, the older brother of Arthur Spiderwick, was eaten by a Troll who had already killed and eaten three other children when Arthur was only eight years old. The newspapers, however, declared Theodore was the latest victim of a vicious bear. The horror happened before Arthur's eyes, and later in life this would make him less objective when studying Trolls.

One hungry River Troll lived under the bridge at Robinson Creek.

Arthur once encountered a female Bauer's Troll who lived in the far north. She liked everything shiny and had adorned herself with the whole collection, as well as pelts from previous meals as protection against the bitter, chilly environment. According to Arthur she smelled like rotten wood. The female had apparently been held prisoner by Humans at some point, as a few iron shackles were tied around her wrist, making the skin calloused and burned.

Another Troll tried to kill a girl named Judy R. during a snowstorm. The Faerie waited outside the window of Judy's parents' room, waiting for the light to burn out. The Troll suggested he and Judy tell riddles to each other. If Judy got one wrong, the Troll would cut the power to the house so he could come in, and if the Troll got one wrong, it may go on to another house with "a child that is not so clever". Judy and the creature told riddles to each other all night, until the sun rose and the Troll turned to stone.

Mole trolls are less known species. One once attacked a mine and ate two miners before it left at daytime unknowingly and turned to stone. In the Spiderwick movie, Redcap sent a Mole Troll to attack Jared and Mallory. The troll was hit by a car as it left the tunnels. It is unknown if it is dead or alive.

Behind the scenesEdit

A Troll is a creature from Norse mythology and Scandinavian folklore.

Tony DiTerlizzi based the design of the River Troll in book 2 on the Troll in the story "Three Billy Goats Gruff" and the Swedish Troll artist John Bauer.


Trivia Edit

  • Bauer's Troll is named after John Bauer, an illustrator who drew many pictures of trolls which greatly resemble the Bauer's Troll.
