After Diagon Alley, Springfield is the cleverest land in the Studios. It's not quite a re-creation of the town of Springfield from The Simpsons—it's more like what would happen if all its characters went to a carnival. 

The area is jammed with inside jokes from the longest-running comedy on TV—for example, Lard Lad Donuts sells “The Big Pink” ($8) and “Ice Cream Conans.” Kwik-E-Mart, free of problematic Apu stereotypes, sells an array of bespoke souvenirs you can only get here (pick up the payphone there, by the way), Moe’s Tavern pours Duff Brewery’s signature quaff—the cause of, and solution to, all life’s problems—and the statue of frontiersman Jebediah Springfield embiggens us all. A Duff pavilion on the water also sells alcoholic Squishees and, in the fall, seasonal Dufftoberfest beer. 

Near the Hollywood end on the lagoon, check out the original locomotive from Back to the Future III. This wasn't in The Simpsons, of course; it's a prominent leftover from the years when Universal Studios was more about big movies.

The big attractions in Springfield are The Simpsons Ride and Kang & Kodos’ Twirl ‘n’ Hurl.
