Bunnicula is a children's book series written by James Howe, featuring a vampire bunny that sucks the juice out of vegetables. Alternatively, Bunnicula is the main title of the first book in the series, published by Atheneum Books in April 1979. The husband-and-wife team James and Deborah Howe wrote it together, but she died before it saw print. About a dozen sequels by James Howe alone were published from 1982 to 2004.
