The portion of the area that borders Rivertown was revamped in 1995 with the addition of a kids' play area, stage and water attraction, and the new sub-section was named "Nickelodeon Splat City". In 2001, the log ride Kings Mills Log Flume was updated with a children's theme and renamed The Wild Thornberrys River Adventure. The Rugrats Runaway Reptar inverted roller coaster was introduced the same year. This expansion into an area that was originally part of Rivertown became known as "Nickelodeon Central". Hanna-Barbera Land was gradually converted over the next several years and eventually renamed "Nickelodeon Universe" in 2006.
