Joe 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 & 6. Steve did not appear in the 2 seasons because he went to college but he took a visit from college in the 100th episode celebration & calls Joe & Blue and is seen as his younger self in Blue's first holiday.
