Blue is the protagonist of Blue's Clues and the only character to appear in every episode of the series and its spin-off, Blue's Room.


The star of Blue's Clues, Blue, is a girl puppy who communicates to Steve and Joe through barks, which they understand. Every episode she initiates a game of Blue's Clues in which she leaves three paw print clues for Steve or Joe and the viewer to find in order to find the answer to a question.


Blue is a blue puppy with darker blue spots and a dark blue nose. Her eyes are white with black pupils. Her tongue is pink if she licks something. She has big, floppy ears.

Her first appearance in an aired episode was in "Snack Time," though she also appeared in the unaired pilot, "Blue Prints". Her last appearance in an episode of Blue's Clues was in "Bluestock", and her final appearance in a Blue's Room episode was in "Music Stars".
