He is the one who starts the whole adventure by rushing by Alice and muttering about being late.
While there are no other rabbits explicitly named in the book, there are a few other rabbit-like creatures that appear:
* The Gryphon has a head and wings of an eagle but the body of a lion, sometimes described as a "gryphon-rabbit."
* The Mock Turtle is described as having a "mock turtle soup" flavor, a reference to the traditional dish made from young sea turtles. This might be seen as a playful allusion to rabbits, as they are often associated with a similar savory taste.
However, the White Rabbit remains the iconic rabbit character of Alice in Wonderland, and the only one explicitly identified as such.
