The Groke from the Japanese–European television-animation Tanoshii Moomin Ikka.
|First appearance||Finn Family Moomintroll|
|Created by||Tove Jansson|
The Groke (original Swedish name Mårran and Finnish name Mörkö) is a fictional character in the Moomin stories created by Tove Jansson. She appears as a ghostlike hill-shaped body with two cold staring eyes and a wide row of white shiny teeth. In the book Who Will Comfort Toffle?, it is mentioned that she has a tail, but it has never been seen. Wherever she stands, the ground below her freezes and plants and grass die. She leaves a trace of ice and snow when she walks the ground. Anything she touches will freeze and on one instance she froze a camp fire by sitting down on it. She seeks friendship and warmth, but she is declined by everyone and everything, leaving her in her cold cavern on top of the Lonely Mountains. On one occasion in a comic, however, she was hailed as a heroine when she, in her constant search for warmth, extinguished a forest wildfire by sitting on it.
Books she appears in 
- 3. Finn Family Moomintroll - This is the first appearance of the Groke, and she is generally played as a frightening villain, though Sniff expresses a bit of sympathy for her, at one point moving himself to tears with a speech on how awful it must be to be so alone.
- 4. The Exploits of Moominpappa - Here, several characters refer to the Groke eating people: The Joxter claims to have a cousin who was eaten by the Groke, and the young Moominpappa saves the Hemulen's Aunt from being eaten by the Groke. She is never actually seen to eat anyone, though, and since the book is written as Moominpappa's memoirs, it's quite possible (and quite in his character) that he exaggerated things a little in order to make himself look more heroic.
- 6. Moominland Midwinter - The Groke makes a couple of cameo appearances, though she comes across as far less villainous and more to be pitied than feared. Too-Ticky even expresses sympathy for her when she wants to warm herself by the fire at the celebration for the sun, and ends up not only scaring everyone away but inadvertently putting out the fire with her own coldness.
- 8. Moominpappa at Sea - In this work, the Groke keeps on going to Moominpappa's island to beg Moomintroll to show her his lantern flame. This story builds on the new angle of the Groke that Too-Ticky offered in Moominland Midwinter, and is generally seen as the most sympathetic portrayal of her in the books, even containing short passages written from her point of view; constantly craving warmth and light but unable to get either. Here the Groke is depicted as a dark and abandoned Moominmamma.
- Who Will Comfort Toffle? - Toffle bites her as he is saving Miffle, however it is not known whether she was holding Miffle hostage or not.
There have been various adaptations of the Moomin books on television. She appears in 1969 anime version of Moomins, where she is different from novels and is depicted as white and depressed. In Polish Moomin TV series she is more like as novels, more dark, but bestial.
The Japanese anime series Moomin includes her as a recurring character. The character is well known about its first appearance in series. Apart from her intimidating appearance the loud growling sounds she utters contributed to this effect. However different language dubs use different growls, as well as different malevolent theme music, which begins to play every time she appears. The Groke's primary introductions were in episode 6, 7 and 22 of the series. It was not until episode 37 that children could start seeing the Groke more sympathetically.
In internet era Groke has became sort of cultural icon of 90's youth. Groke had inspired many indie-artists in Scandinavian, such as rock bands and graphic artists. For example Finnish thrash metal band called Groke's Clan has been named after the Groke. Also, Providence-based doom act Groke take their name from the character. There are also many Groke videos (usually horror themed) on YouTube, which represent people's traumas about the character. In 2011 Finnish independent film production group called Aseman Lapset made a full-length movie about the subject. The film, simply called Mörkö (The Groke), includes the Groke as "a main villain", but also deals with subjects of childhood fears and traumas in a form of horror film. This non-commercial movie was released in YouTube.
