The Mall of America has a gross area of 4,870,000 sq ft (452,000 m²) or 96.4 acres (390,000 m²), enough to fit seven Yankee Stadiums inside, with 2,500,000 sq ft (230,000 m²) available as retail space. The mall is nearly symmetric, with a roughly rectangular floor plan. More than 530 stores are arranged along three levels of pedestrian walkways on the sides of the rectangle, with a fourth level on the east side. Four anchor department stores are located at the corners. The mall is organized into four different zones, each of those zones had its own decorative style until a series of renovations from 2010 to 2015 led to a unified and more luxurious style, as well as to coincide with the mall’s first major expansion. Despite Minnesota’s cold winters, only the mall’s entrances and some below ground areas are heated. Heat is allowed in through skylights above Nickelodeon Universe. The Mall of America originally had Camp Snoopy, but due to an expired contract the park was taken over by a new organization. The majority of the heat is produced by lighting fixtures, other electric devices, and people in the mall. In fact, even during the winter, air conditioning systems may still be in use during peak hours to ensure a comfortable shopping environment. Although the common areas are unheated, the individual stores do have heating systems.
Nickelodeon Universe is an indoor theme park in the center of the mall. The park features roller coasters, among numerous other rides and attractions, 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 and Avatar Airbender, and a thrill ride called BrainSurge. The latter roller coaster 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. The Mall recently added Crayola Experience and FlyOver America to the list of family attractions.
