Donovan Patton
According to Traci Paige Johnson, one of the producers and creators of "Blue's Clues", Patton's character was more like a preschooler and more innocent than Steve. Angela Santomero, another producer and creator, stated that Patton's characterization as Joe brought him closer to the preschool viewer as Joe was more willing to "jump into a problem rather than figure it out first like Steve". Patton liked working on "Blue's Clues" because, as he stated, "I got to go be a kid for twelve hours a day". He called the show's crew "a real fun little family" and a "well-oiled machine" by the time he joined the show. Patton remained on the show for 50 episodes, until it ended its run in 2006, and also appeared in its spin-off, "Blue's Room", which premiered in 2004. Several years later, Patton said he had not yet grasped the enormity of replacing Burns, even after he became a parent and witnessed the show's effect on his own children. He admitted that he preferred when his two-year-old daughter watched the Steve episodes.
