The Caterpillar is a fictional character appearing in Lewis Carroll's 1865 book Alice's Adventures in Wonderland.
The Caterpillar using a hookah; an illustration by John Tenniel. The illustration is noted for its ambiguous central figure, whose head can be viewed as being a human male's face with a pointed nose and protruding chin or being the head end of an actual caterpillar, with two "true" legs visible.
