In the center of the Mall of America is a seven-acre amusement park.  Nickelodeon Universe features rollercoasters, thrill and family rides as well as attractions for all ages.

The mall is built on the former site of Metropolitan Stadium where baseball's Minnesota Twins and football's Vikings called home.  A plaque in the amusement park commemorates the site of home plate, from which Hall of Famer Harmon Killebrew once launched a 520-foot home run.
