Mummitrollet is the Norwegian name for Moomintroll, the central character in Tove Jansson's Moomin stories, first published in book form in 1945. The Hattifatteners, called Hattifnattene in Norwegian, are pale, silent figures who travel in groups, are drawn to electrical storms and cannot speak or hear in the usual way. Through books, comics and television adaptations the Moomins became a Nordic childhood staple, and short dubbed lines like this one now circulate online as in-jokes among fans who grew up hearing the characters in Norwegian.
