The seventh season of Teenage Mutant Ninja Turtles, titled Back to the Sewer, aired on Saturday mornings on the CW4Kids on CW Network in 2008-2009. With this season, the show moved from Fox's 4Kids TV lineup to the CW. The season began with the episode "Tempus Fugit" which aired on September 13, 2008. It is followed by the TV special Turtles Forever. Cody Jones is able to finally repair the Time Window, but parts with the Turtles and Splinter can return to 2006. However, Viral, who had survived her defeat in the previous season, hacks into the time window, taking control of it and sending the Turtles, Splinter and Serling (who fell in by accident) to various eras in attempts to kill them. Just as the group is able to return home, Viral attacks Splinter, shattering him into countless bytes of data scattered across the Internet. The Turtles and Serling resolve to recover Splinter's bytes and return him to his whole self by digitizing themselves and entering cyberspace to find them.
