Much of the original theming in the Camp Snoopy fountain and all around the park was already toned down by the time the rights to the Peanuts characters were lost.

TMNT Shellraiser, a Gerstlauer Euro-Fighter, would hold the record for the steepest roller coaster drop at 121.5 degrees, and is based on a model seen in Japan.

American Dream said it will add eight more rides to the Nickelodeon Universe theme park, building on its early success.

Concept artwork that was released during the theme park's announcement on July 26, 2018 showcases rides that are at the American Dream location, as well as several new attractions.
