A Mysterious Discovery in the Movie Theater
The story begins with Harold, the Monroe family's shaggy dog, narrating the events that unfolded after the family's visit to a Dracula movie. Mrs. Monroe, known for her soft heart, discovers a small, dark rabbit abandoned in the movie theater. Despite Mr. Monroe's initial reluctance and the children, Toby and Pete, being asleep, Mrs. Monroe insists on bringing the creature home. Harold is intrigued by the new addition, but Chester, the sophisticated Siamese cat, senses something amiss. Chester, an avid reader of mystery novels, views the bunny with suspicion from the moment it enters their home, setting a tense tone for the new pet's arrival.
Bunnicula's Strange Habits Emerge
The newly named Bunnicula, after a family vote, is an unusual pet. He refuses to eat the carrots and lettuce offered to him, confusing everyone. The next morning, the family discovers a peculiar sight: a tomato in the kitchen has been drained of its color, turned completely white, and shriveled. Mrs. Monroe attributes it to a plant disease, but Chester is immediately suspicious. He observes Bunnicula's nocturnal habits and theorizes that the bunny is a vampire, drawing sustenance not from blood, but from vegetables. Harold, though initially skeptical, finds Chester's theories increasingly compelling as more vegetables are found mysteriously whitened.
Chester's Growing Obsession and Research
As more vegetables, including celery and zucchini, are discovered pale and lifeless, Chester becomes obsessed with proving Bunnicula's vampiric nature. He spends his days reading books on vampires and the supernatural, much to Harold's amusement and occasional annoyance. Chester tries to explain his findings to Harold, detailing the characteristics of vampires and how Bunnicula fits the description, particularly his fangs and nocturnal activity. He even tries to show Harold a picture of a vampire in one of his books. Harold, while finding Chester's theories fantastical, cannot deny the mounting evidence of the whitened vegetables and Bunnicula's peculiar behavior.
The First Attempt to Ward Off Evil
Convinced that Bunnicula is a vegetable vampire, Chester decides he must act. His first attempt involves hanging garlic around Bunnicula's cage, believing it will ward off the evil or at least prevent Bunnicula from further draining vegetables. The strong smell of garlic, however, causes discomfort for everyone in the house, particularly Harold, and results in Mrs. Monroe removing it, thinking it is a strange new household odor. Chester's efforts are met with misunderstanding from the human family, who remain unaware of the true nature of their furry pet. This setback only fuels Chester's determination to find a more effective solution.
The Steak-and-Stake Incident
Chester escalates his attempts to confront Bunnicula's vampirism. Remembering a detail from his vampire books, he decides that a stake through the heart is the only way to stop a vampire. Unable to find a wooden stake, he improvises with a steak knife and, in a moment of misguided zeal, tries to 'stake' Bunnicula. Harold intervenes, preventing serious harm, but not before Bunnicula is startled and upset. The commotion draws the attention of the Monroe family, who find Bunnicula visibly distressed and Chester looking suspicious. They interpret Chester's actions as jealousy and take Bunnicula to the vet, believing he is ill, completely missing the true reason for the incident.
Bunnicula's Decline and Chester's Guilt
Following the 'staking' incident and the subsequent vet visit, Bunnicula grows increasingly weak and lethargic. He stops moving much and looks sickly, which deeply concerns the Monroe family. Chester, witnessing Bunnicula's decline, begins to feel guilty. Despite his conviction that Bunnicula is a vampire, he did not intend to cause the bunny actual harm. He watches as the family tries various foods to tempt Bunnicula, all to no avail. Harold observes Chester's conflicted emotions, seeing that the cat's scientific curiosity is now tinged with genuine concern for the little rabbit's well-being.
The Lettuce Leaf Solution
As Bunnicula's condition worsens, the Monroe family considers drastic measures, even calling the vet again. Harold, who has been quietly observing, has a sudden insight. He recalls Bunnicula's fangs and the whitened vegetables. He realizes that Bunnicula does not just eat vegetables; he drains them. Taking a fresh lettuce leaf, Harold gently places it near Bunnicula's fangs. To everyone's astonishment, Bunnicula bites into the leaf, and the leaf quickly shrivels and turns white, while Bunnicula slowly regains some of his color and energy. It becomes clear that Bunnicula needs to sink his fangs directly into the vegetables to feed.
A New Feeding Routine for Bunnicula
With Harold's discovery, the mystery of Bunnicula's health is solved. The Monroe family, though still unaware of the 'vampire' aspect, establishes a new feeding routine for Bunnicula. They learn to leave fresh vegetables in his cage, allowing him to 'drain' them at his leisure. Bunnicula quickly recovers his health and vitality, becoming a lively, if still peculiar, pet once more. Chester, relieved that Bunnicula is no longer suffering, reluctantly accepts the bunny's unique dietary needs. The strange occurrences of whitened vegetables continue, but they are now understood, and the household returns to its usual, albeit slightly more eccentric, rhythm, with Harold continuing to document their adventures.
