What is a nargle?

Nargles are fictional creatures believed to inhabit mistletoe bushes according to the Harry Potter book series by J.K. Rowling. They were first mentioned in the book "The Tales of Beedle the Bard" and later made appearances in "Harry Potter and the Order of the Phoenix" and "Harry Potter and the Half-Blood Prince."

Nargles are described as being very small and elusive creatures, making them difficult to detect. They are known for their mischievous nature, being blamed for causing untidy hair, lost items, and other small annoyances. Luna Lovegood, a character in the Harry Potter series, is particularly fascinated by nargles and often references their existence.

While nargles are primarily seen as fictional creatures within the Harry Potter universe, they have gained some popularity in popular culture. They are sometimes referenced humorously during discussions about misplacement of items or when someone's hair appears disheveled.

It is important to note that nargles do not exist in the real world; they are purely a creation of J.K. Rowling's imagination for the purposes of her books.
