Despite his resemblance to Bela Lugosi's portrayal of Dracula, The Count's status as a vampire is questionable.
While the specification chart in the 1998 style guides says Count von Count's only similarities to Dracula are visual, his profile on the Sesame Workshop webpage suggested that he is related to the famous vampire.
Additionally, the creator of Count von Count, Norman Stiles, said to performer Jerry Nelson that The Count is "a vampire, but not a real vampire."
However, in his WIRED interview, Count von Count said in response to the question "Is the Count on Sesame Street a vampire?": "Yes, but I am a vampire with an unquenchable thirst for numbers." This is in reference to traditional vampires who exhibited arithmomania.
Even though Count von Count has never been explicitly labeled as a vampire on screen, the current information leaves it ambiguous at best.
