Joe is Steve's younger and taller brother. When Steve leaves for college, Joe stays with Blue and becomes the new host and the main protagonist for the rest of the show (which means seasons 5 to 6). Joe loves squares, like the ones on his shirt, and cannot wait to play Blue's Clues. Like Steve, Joe's favorite color is green (as proven in the episodes "Steve Goes to College", "Colors Everywhere!", and "The Big Book About Us"), even though he is seen wearing five other colored shirts, unlike his brother who wore just a green shirt. He also has a stuffed duck named Boris and his notebook is shaped just like the Thinking Chair. As of Blue's Clues & You!, he works at the Present Store. He is played by Donovan Patton.
Joe is blue's second caregiver and he took over the complete role of Steve as the host after the 5th season began in 2002. This was a difficult task for the film people of the show, for Steve, and for many of Steve's fans. After the 6th season started, Nick Jr. decided to play reruns of episodes from seasons 1-4, and still does to this day, making it easier for Steve fans to get used to the new host. Then, Nick Jr. decided to play returns of episodes from seasons 5 and 6. Steve did not appear in the last 2 seasons because he went to college but he took a visit from college in the 100th Episode Celebration and calls Joe and Blue and is seen as his younger self in Blue's First Holiday.
