"Henny Penny", more commonly known in the United States as "Chicken Little" and sometimes as "Chicken Licken", is a European folk tale with a moral in the form of a cumulative tale about a chicken who believes that the world is coming to an end. The phrase features prominently in the story, and has passed into the English language as a common idiom indicating a hysterical or mistaken belief that disaster is imminent. Similar stories go back more than 25 centuries and "Henny Penny" continues to be referred to in a variety of media. The story and its name The story is listed as Aarne–Thompson–Uther type 20C, which includes international examples of folktales that make light of paranoia and mass hysteria. There are several Western versions of the story, of which the best-known concerns a chick that believes the sky is falling when an acorn falls on its head. The chick decides to tell the king and, on its journey, meets other animals (mostly other fowl) which join it in the quest. After this point, there are many endings. In the most familiar, a fox invites them to its lair and then eats them all. Alternatively, the last one, usually Cocky Lockey, survives long enough to warn the chick, who escapes. In others all are rescued and finally speak to the king. In most retellings, the animals have rhyming names, commonly Chicken Licken or Chicken Little, Henny Penny or Hen-Len, Cocky Locky, Ducky Lucky or Ducky Daddles, Drakey Lakey, Goosey Loosey or Goosey Poosey, Gander Lander, Turkey Lurkey and Foxy Loxy or Foxy Woxy. In the United States, the most common name for the story is "Chicken Little", as attested by illustrated books for children dating from the early 19th century. In Britain and its other former colonies, it is best known as "Henny Penny" and "Chicken Licken", titles by which it also went in the United States. History The story was part of the oral folk tradition and only began to appear in print after the Brothers Grimm had set a European example with their collection of German tales in the early years of the 19th century. One of the earliest to collect tales from Scandinavian sources was Just Mathias Thiele, who in 1823 published an early version of the Henny Penny story in the Danish language. The names of the characters there are Kylling Kluk, Høne Pøne, Hane
