Who says 'Curiouser and curiouser!' in Wonderland?

Alice says “Curiouser and curiouser!” in Wonderland.

She speaks the line after a series of astonishing changes in her size leave her physically and emotionally disoriented. In Carroll’s original 1865 novel, Alice is trying to make sense of a world where ordinary rules no longer apply: bottles change her height, animals talk, and familiar language turns into riddles and wordplay. Her exclamation captures her amazement at the absurdity around her.

The phrase is especially memorable because “curiouser” is a deliberately playful, nonstandard comparative form of “curious.” Carroll uses unusual grammar throughout the Alice books to create a comic atmosphere in which logic is constantly stretched. The line is sometimes mistakenly attributed to the Mad Hatter or the Cheshire Cat because both are strongly associated with Wonderland’s strange conversations, but the speaker in the book is Alice herself. The quotation has since become a popular expression for something increasingly strange or intriguing.
