Nickelodeon is set to bring back four beloved animated series to its TeenNick and Nick Jr. linear channels starting Monday, September 8, 2025. The iconic Nicktoons Rugrats, Hey Arnold!, and The Fairly OddParents will light up late-night and early-morning schedules on TeenNick, while the imaginative preschool series Wallykazam! makes a triumphant return to Nick Jr.’s daytime lineup as first spotted by NickaLive.
Kicking off on September 8, TeenNick will dedicate its late-night and early-morning hours to a marathon of fan-favorite Nicktoons, airing in blocks of back-to-back episodes. The schedule begins at 11:04 p.m. EDT with four episodes of The Fairly OddParents, the whimsical series following Timmy Turner and his magical fairy godparents, Cosmo and Wanda, as they navigate the chaos of childhood wishes. From 12:45 a.m. to 2:24 a.m., viewers can relive the adventures of Tommy Pickles and his toddler crew in four episodes of Rugrats, the groundbreaking show that captured the wonder of a baby’s perspective. Rounding out the night, Hey Arnold! takes over from 2:24 a.m. to 6:00 a.m. with an impressive nine-episode block, showcasing the heartfelt stories of Arnold Shortman and his diverse group of friends in the urban jungle of Hillwood.
Meanwhile, Nick Jr. is set to enchant its preschool audience with the return of Wallykazam!, the imaginative series that blends animation, music, and early literacy skills. Starting September 8, Wallykazam! will air daily at 9:00 a.m. EDT, following Wally Trollman and his dragon friend Norville as they embark on magical word-based adventures in a fantastical forest. The show’s focus on vocabulary and creativity makes it a perfect fit for Nick Jr.’s educational yet entertaining lineup.
The return of these shows comes as Nickelodeon continues to balance its programming with a mix of fresh content and nostalgic classics. Rugrats (1991–2004), a pioneer in animated storytelling, redefined children’s television with its unique perspective and enduring charm. Hey Arnold! (1996–2004) remains a beloved staple for its emotional depth and depiction of urban childhood, while The Fairly OddParents (2001–2017) is celebrated for its zany humor and imaginative scenarios. Wallykazam! (2014–2017) adds a modern twist, engaging young viewers with interactive storytelling and wordplay.
The programming blocks will air daily on TeenNick and Nick Jr., with potential for additional timeslots based on viewer response. For those looking to catch up, episodes of these series are also available on streaming platforms like Paramount+, though the linear channel experience promises a shared nostalgic journey for fans tuning in live.
Nickelodeon encourages viewers to join the conversation online using #NickNostalgia and to check local listings for exact airtimes. Whether you’re a ‘90s kid reminiscing about after-school cartoons or a parent introducing your children to these classics, September 2025 promises to be a month of animated magic on TeenNick and Nick Jr.
