Nickelodeon Universe is an indoor theme park in the center of the mall.
The park features roller coasters, among numerous other rides and attractions, including many not related to Nickelodeon, and is the largest indoor theme park in the United States.
Unlike many indoor amusement parks, Nickelodeon Universe has a great deal of natural foliage in and about the park, and its floor has a wide variance in height – the highest ground level in the park is 15 feet (4.6 m) above the lowest.
The rides include the roller coasters SpongeBob SquarePants Rock Bottom Plunge, Fairly Odd Coaster, Back at the Barnyard Hayride and Avatar Airbender, and a thrill ride called BrainSurge.
The latter attraction bills itself as a "rather peculiar" ride.
It also has a miniature golfing section called Moose Mountain.
This miniature golf course features eighteen holes and a relatively fast astroturf surface.

At the Sea Life Minnesota Aquarium, guests travel through a 300-foot-long (91 m) curved tunnel through 14 feet (4.3 m) of water to view over 4,500 sea creatures including sharks, turtles, stingrays and many more.
Sea Life Minnesota Aquarium offers special events such as sleepovers, scuba diving, snorkeling and birthday parties.
