In 2013, the ride became the centerpiece of a themed Simpsons area at both parks, based on the fictional town of Springfield depicted in the animated series.

The attraction is more than four minutes long and features two pre-show line queues that guests experience before boarding the ride.

[1] The building was given a complete overhaul; the cars were changed and the original Intamin mechanics system was updated by Entech Innovative Engineering.

[12][13] The construction began at Universal Studios Hollywood in mid-September 2007, with the disposal of the building's Back to the Future insignia.

In April 2022, the Universal Studios Hollywood ride reopened from refurbishment with an updated soundtrack and slightly altered timings.

As a result of the Walt Disney Company's acquisition of 20th Century Fox in 2019, The Simpsons are now a Disney-owned intellectual property.

[27] Guests walk through a 32-foot (9.8 m) head of Krusty the Clown[3] as they enter the ride's line queue, which leads them into a pavilion under various circus tents themed to carnival stalls.

A variety of posters are on display advertising attractions at Krustyland, while television monitors stationed around the queue play video clips from the Krusty the Clown television show, animated footage from Krustyland, and clips from episodes of The Simpsons, many of which are theme park-related and hail from episodes such as "Itchy & Scratchy Land" and "Selma's Choice".

TV screens line the walls to both the left and right, displaying the residents of Springfield running through midway booths at the park.

Sideshow Bob sneakily appears in a Scratchy costume when Krusty isn't looking and steps on Homer Simpson's foot, causing him to yell "D'oh!

The next pre-show is themed to a funhouse room, where Krusty leads the group into a backstage area revealing that the park is powered by a nuclear reactor.

Grampa suddenly falls asleep while Maggie crawls into the nearby nuclear reactor room, causing her to grow larger.

He can then be seen reading his textbook, which is upside down, while quiet elevator music reminiscent of "The Simpsons Theme" begins playing in the background.

The rider's vehicle plunges soon after, revealing they are on the "Tooth Chipper" roller coaster (which was scheduled for demolition) involving a variety of drops and turns.

The "steel" wrecking ball breaks free from its cable and rolls along the track chasing Homer and the riders.

His actions trigger a trap that destroys their surroundings, transporting them to "Krusty's Wet and Smoky Stunt Show", running over a popcorn seller in the process.

Upon reaching the attraction's exit, it suddenly explodes, sending them racing in circles while dragging Homer and the riders behind them.

After a series of jumping ramps, the group fly through a tipping metal water tower, where they crash at the edge of the attraction and encounter Bob again, who cuts a large hole into hell with a buzz saw.

Maggie, now giant-sized from the effects of the reactor room depicted earlier, reappears and grabs Bob, causing his robotic panda to fall into the hole.

Maggie appears and ends the ride by pushing down a large Krusty head sign directly over the Simpsons.

)[8] A large portion of the World Expo area at Universal Studios Florida and a portion of the Upper Lot at Universal Studios Hollywood were converted into a new themed area called Springfield (although Florida's version of Springfield would actually be a subsection of World Expo until 2016), based on iconic landmarks from The Simpsons such as Krusty Burger, Frying Dutchman, Lard Lad Donuts, Moe's Tavern, and a Duff Brewery.

[21] Brady MacDonald of the Los Angeles Times described the ride as "visually stunning" and said it "truly delivers — with loads of in-jokes and satire for serious fanatics and tons of thrills and fun for casual fans.

"[36] Jay Cridlin of the St. Petersburg Times wrote that "the ride is packed with more original, funny material than you'd expect to see in a sitcom, much less a theme park."

[37] The Universal Studios Florida version of the ride hosted its one millionth rider on July 14, 2008, reaching the milestone faster than any other attraction in the resort.

The park identified the source of the oil but could not determine the cause of the incident, and the unaffected ride vehicles remained open.
