This is a list of toys created by the popular children's television network Nickelodeon.
A number of molding substances for children's play were created and sold by the American children's television channel Nickelodeon and toy company Mattel in the 1990s. Like most molding compounds, they could be kept in their container to retain plasticity, or molded and allowed to harden overnight. They featured a wide variety of compounds with different attributes.
Nickelodeon's first compound, whose idea was first taken from the classic Nickelodeon show You Can't Do That on Television. Nickelodeon Slime was first manufactured in the 1980s. Nickelodeon slime was sold again in Fall 2008 but was released by Jakks Pacific. It was released again in March 2012 along with Gak and Floam. In 2017, they were all rereleased with logo changes, and can be found at Toys "R" Us & Walmart.
Green Slime Shampoo was the first soap-related compound based on You Can't Do That on Television. Its premise was to "get slimed in your own shower". It had green shampoo that got you clean instead of getting slimed (hence its slogan: "Gets you clean, but won't turn you green!"). This was also featured as a prize on a few episodes of Double Dare.
Green Slime Liquid Soap was another soap-related compound based on You Can't Do That on Television, but it was less popular than its predecessor, Green Slime Shampoo. It was introduced as an introductory free-pack if the predecessor was bought from the TV offer.
Nickelodeon/Mattel's most popular compound; the idea was taken from the Nickelodeon show Double Dare and Wham-O's Super Stuff from the mid-1960s. The original edition was manufactured in 1992, and then re-issued in 1994 for the Nickelodeon Deluxe Gift Set which included one of Nickelodeon Gak and two canisters of Nickelodeon Floam. It was marketed on the fact that, unlike most of the compounds, it made a "fart" noise when squeezed into its clear, star-shaped container. Gak, Gak-In-The-Dark, Gak Vac, Smell My Gak, and the Gak Copier are now being resold today with modern-day Nickelodeon branding.
