Tickety Tock, usually called Tickety for short, is a main character on Blue's Clues.
Tickety is a friendly alarm clock who lives on top of Blue's nightstand. She enjoys ringing her bells, which she uses to wake up everyone in the Blue's Clues house. Tickety often needs help moving her clock hands. She and Blue both hope to become teachers when they grow up.
Tickety is mostly pink. She has silver bells and black eyes, hands and feet. The periphery of her dial is numbered 1 to 12. The number 12 is occasionally replaced by a different symbol fitting the theme of a specific episode.
Tickety appears in most episodes of Blue's Clues. Her first appearance was in "Snack Time". Her last appearance was in the series finale, "Bluestock."
Tickety's favorite nursery rhyme (and the answer to Blue's Clues in the episode of the same name) is "Hickory Dickory Dock" due to its focus on a clock.
In seasons one through three, Tickety is one of four characters to appear in the credits sequence. The others are Blue, Mr. Salt, and Mrs. Pepper.
