Which character counts everything and has a vampire-like appearance?

The character who counts everything and has a vampire-like appearance is The Count. His full name is Count von Count, a Sesame Street Muppet whose obsession with numbers turns ordinary counting into his signature comedy.

The Count first appeared in 1972 and was originally portrayed by puppeteer Jerry Nelson. His design and mannerisms parody classic vampire imagery: he wears a cape, lives in a cobweb-filled castle, and is associated with bats, thunder, lightning, and an unmistakable “Ah-ah-ah!” laugh. Unlike a frightening vampire, however, he is friendly and primarily exists to help children practice counting.

The character’s name is also a wordplay joke. “Count” can mean a nobleman, as in Count Dracula, or the act of determining how many objects there are. That double meaning explains both his aristocratic vampire look and his educational role. He has sometimes been called simply “the Count,” which is the canonical answer accepted for this question.

A frequently mentioned detail is that his favorite number is 34,969, a perfect square: 187 multiplied by 187. After Nelson’s death, Matt Vogel took over the character’s voice and puppetry.
