The "Blue's Clues" gang is busy preparing for a musical they're staging in the backyard, but when Tickety Tock---Blue's duet partner---loses her voice, they search for a replacement using a game of Blue's Clues. Also: wannabe "song maker-upper" Steve (Steven Burns) learns about notes, rhythm, tempo and soul from G-Clef (voice of Ray Charles); and Periwinkle practices for what he mistakenly thinks is a magic show. Voices include...Blue: Traci Paige Johnson. Tickety Tock: Kelly Nigh. Periwinkle: Cameron Bowen. Mailbox: Seth O'Hickory.
