The Munroe family return from a trip to the movies with a new addition to the family - Bunnicula! A small, cute, furry bunny they found abandoned on a seat. Harold and Chester are somewhat put out - just who is this strange creature? And doesn't he have the strangest staring eyes, and distinctly fang-like teeth? Chester is convinced that Bunnicula is no ordinary rabbit, and Harold simply humours him. But when a white vegetable is found in the fridge, Chester has all the proof he needs. Bunnicula is sucking the vegetables of all their colour - he's a vampire! Chester and Harold try every anti-vampire remedy they can think of, but time is running out. Today, vegetables . . . Tomorrow, the world!
