His memorable phrase is a breathy "Whooo ... are ... you?". In the Disney animated movie, this line is visualised as exhalations of smoke in the shapes "O", "R" and "U". Alice remarks in the original story that the Caterpillar will one day turn into a butterfly, and in both the 1999 television film and Disney's 1951 version he does so in Alice's presence. He is voiced by Richard Haydn. The Caterpillar in Alice in Wonderland is a blue creature who appears to be smoking a hookah. He is seen as a very violent character as he screams at Alice quite often during the scenes he appears in. He blows smoke in Alice's face and when she needs help he ignores her. He is a quite mean character as he provides little to no help to Alice and ends up confusing her more while she is trapped in Wonderland. He then ignores her and turns into a butterfly and flutters away not caring if Alice makes it out alive or not. He also instructs her to eat a mushroom but doesn't tell her what it does thus putting her into possible danger. He reappears one final time during the ending chase, still in butterfly form but once again smoking on his hookah, and again ignoring Alice when she asks for his help escaping the Queen of Hearts.
