In 1995, "Nickelodeon Splat City" opened at three former Paramount Parks: California's Great America, Kings Dominion and Kings Island. These attractions were inspired by the game shows that aired on the television network and generally involved slime. In 1999, Kings Dominion closed Nickelodeon Splat City in preparation for the opening of its 2000 attraction, Nickelodeon Central. "Nickelodeon Central" brought a retheme of many of the park's children's rides as well as the addition of new ones. Kings Island followed suit, closing its Splat City in 2000 and opening "Nickelodeon Central" in 2001. This area would later be expanded and renamed "Nickelodeon Universe" in 2006.
