Muppet Fact #1758
The Count's pet cat—Fatatita—has had her name spelt and pronounced a variety of different ways throughout her time appearing on Sesame Street and other related media.
In her first appearance, Count von Count calls her "Fatatita." In The Sesame Street Dictionary, the Count's 1998 Sesame Street profile, and Ernie's Finish the Picture, her name is spelt "Fatatatita," with an extra syllable. Additionally, in The Sesame Street Sun, she is called "Ftatateeta."
