Blue's Clues is an American children's television series airing on the Nickelodeon family of channels. The series takes place inside a world in which everything is made of paper cutouts, clay, and other craft materials. It is presented by a live-action human host who lives in a yellow house inhabited by anthropomorphic everyday objects. Steve Burns hosted the series from its debut in 1996 until 2002, when the part was taken over by Donovan Patton. The program features an ensemble cast of animated characters who interact with the host. Co-creator Traci Paige Johnson voices the title character, a dog named Blue who communicates through distinctive barks. The series' composers Michael Rubin and Nick Balaban voiced Mailbox and Mr. Salt, respectively. In addition to the main characters, the show included various newly-introduced recurring characters and guest stars throughout its run. Some guests appeared as live-action companions of the host, while others voiced an animated cameo role. When a spin-off series titled Blue's Room premiered in 2004, a group of puppet characters were introduced as new friends of Blue. A reboot titled Blue's Clues & You! premiered in 2019, with Joshua Dela Cruz as the new host. Main Blue (voiced by Traci Paige Johnson in Blue's Clues and Victoria Potencorvo and puppeteered by Leslie Carrara-Rudolph in Blue's Room) is a playful and energetic 5-year-old female dog with light blue fur and dark blue spots. She cannot talk but communicates with her owners, Steve, Joe, and Josh, through barks that they interpret based on her tone and expression. In each episode, she plays a game called Blue's Clues, in which she leaves three blue paw print clues for the host and viewers to find in order to answer a question. She has the ability to enter storybooks and picture frames by "skidooing" into them with a special dance routine. In the sixth season, she is granted a magic playroom called Blue's Room in which she can interact with the viewer and a cast of live-action puppet characters. In most animated appearances, she is one of the series' creators. Johnson was cast as the character's voice because out of the crew, she was able to sound the most like a dog. Steve (played by Steve Burns) is the host for the show's first four seasons (and one of the former hosts of the Blue's Clues franchise). He is Blue's owner and caregiver. He wears
