[4] Under Perkins' ownership, the park continued to prosper and additional amusements were added, including a 300-foot-diameter pool that became known as Lake Takadip.

By the 1980s, the park stopped selling individual ride tickets and began charging a "pay one price" admission.

Six years after the opening of Black Widow, the Wildcat was removed and moved to the late Rocky Point Park in Rhode Island.

A majority of the ride was demolished in 1989 to make way for Wild River Falls, a waterslide complex consisting of three sets of slides: Riptide, Blue Lightning and Pipeline.

A popular attraction, Wild River Falls remained in operation until the opening of the Island Kingdom Waterpark in 1997.

[15] The plan died after Agawam voters rejected a non-binding referendum in support of casino gambling in November.

The Island Kingdom Waterpark was an expansion to the park that featured a children's water play area, various slides, and a wave pool.

To make room for this expansion, the parking lot was relocated to the other side of the roadway in former farmland and significantly expanded.

The park also added The Hellevator, an S&S Worldwide Turbo Drop tower measuring 21 stories tall, which was originally painted red.

Additions included a new slide tower named Shark Attack and a second wave pool called Hurricane Bay.

The park also added Flashback, a relocated Vekoma Boomerang from Kentucky Kingdom, which replaced the Black Widow and Rotor in the North End.

In 2006, Splash Water Falls and Catapult, an S&S Power Sky Swatter, were added to the park, two relocated rides from the recently closed Six Flags AstroWorld.

The track was repainted purple with dark blue supports, and multiple special effects were added; including building structures that give riders the impression of speeding through a city, rings in the shape of Bizarro's S shield that the train passes through, and flame effects.

In 2011, Gotham City Gauntlet: Escape From Arkham Asylum opened up in the DC Super Hero Adventures section of the park.

This ride replaced the football field and was placed on the same plot of land that the canceled Dark Knight Coaster was supposed to be built on.

At the conclusion of the 2013 season, Taz's DareDevil Dive and Twister, a Huss Topspin located in Rockville, were removed.

In 2017, The Joker, a 4D FreeFly coaster, was installed on the former site of Splash Water Falls, which closed toward the end of the 2016 season.

This included retheming Mind Eraser to The Riddler Revenge, which received a new color scheme with green track and yellow supports.

For the 2019 season, Cyborg: Hyper Drive, a spinning flat ride, was installed inside the former Hall of Justice building in the DC Super Hero Adventures area of the park.

For the 2020 season, the park announced the addition of Supergirl Sky Flyer, a Zamperla Endeavour located on the site of the former Kryptonite Kollider.

In July 2021, a tree fell onto Fireball during a thunderstorm, extensively damaging the attraction and leaving it closed for the rest of the season.

The plot of land occupied by Goliath was left as a large grass area and known as Crackaxle Commons for the 2023 and 2024 seasons.

Quantum Accelerator is an Intamin Straddle Coaster that will open in 2025, featuring two launches up to 45 MPH and 11 airtime moments.

The line-up of Looney Tunes characters includes: Bugs Bunny, Daffy Duck, Tweety Bird, Sylvester, Foghorn Leghorn, Porky Pig, Petunia Pig, Pepé Le Pew, Roadrunner, Wile E. Coyote, Marvin the Martian, Taz, Granny, Lola Bunny, Elmer Fudd, Speedy Gonzales, Yosemite Sam and Gossamer.

This addition brought the following characters to the park: Batman, Robin, Aquaman, Wonder Woman, Hawkgirl, Green Lantern, The Flash, The Joker, The Riddler, Sinestro, Cheetah, Lex Luthor and Captain Cold.

The Hall of Justice is located in the building where the Jokers Wild Card flat ride used to be, transforming it into a secret lair.

It was the unique brainchild of world-renowned creative director Gary Goddard and featured five custom-designed floats, 65 performers, and more than 35 support staff members and technicians.

Each float was adorned with vibrant-multicolor lights that illuminate the park and surrounded the streets with custom-composed cirque-inspired music.

The parade featured drummers, puppeteers, singers, dancers, and kinetic stilt walkers to create an unparalleled nighttime spectacular.

This transformation include the addition of Halloween decorations to several of its midway areas (making them Haunt Zones with roaming characters monsters), several shows and five premium haunted attractions: Nightmares, Terror Tales, The Aftermath: Zombies Revenge, Slasher Circus 3D and Midnight Mansion.
