NickALive has confirmed that season 3 of the Nickelodeon TMNT series will indeed return on Sunday August 2nd. They also have reported that the 2003 TMNT cartoon will be airing on Nicktoons beginning with a marathon on July 11th.
I was watching TMNT on Nicktoons the other night and saw a commercial air that confirmed this as well. Nicktoons is calling it “Turtle Nation” and it appears we will be getting movies and cartoons starting July 11th. Keep checking back for more!
