Halloween Horror Nights is one of Universal's most highly anticipated annual events. With impressive scare zones and immersive haunted houses at every turn, changing each year, guests in search of a good fright are in for the ride of their lives.

Universal is well-known for not pulling any punches when it comes to the scare factor during this yearly event. Blood, guts, and jump scares are featured at every turn and it is not typically recommended or marketed toward younger audiences. This year, Universal is celebrating its 31st Halloween Horror Nights, so to join in on the scares, it is time we talk about one of the most controversial entries in this event's history at the resort.

In 2002, Universal was gearing up for its 12th annual Halloween Horror Nights event which was to be held for the first time at the newly opened Islands of Adventure theme park. The icon of the year was planned to be a little girl by the name of Cindy. Cindy Caine was the daughter of Dr. Albert Caine (better known as the Caretaker) and the original plot involved Cindy taking over the various islands and turning them into her playthings.

After a handful of child abductions in the area during the year, Cindy's idea was scrapped and the icon of Islands of Fear became her father, the Caretaker. The former surgeon turned mad scientist seized control of the Islands with the help of his faithful servants of darkness and brought forward some of the most controversial haunted houses in Horror Nights history. With a total of five haunted houses, six scare zones, and four shows, Islands of Fear officially opened to the public on October 4, 2002.

Starting in the Jurassic Park section was a unique scare zone called JP Extinction. After an experiment gone wrong unleashed a swarm of human-dinosaur hybrids around the park, guests would have the option to enter the Project Evilution haunted house. While being chased by hungry Dino-Men and escaped carnivorous dinosaurs, guests would follow the former Triceratops Encounter trail through the woods.

Agitated triceratops animatronics bellowed behind the strobe lights, and toward the end of the trail, guests would bear witness to a gruesome sight--the head of a decapitated triceratops, suspended with wires and still dripping with blood.

That wasn't all, there was still more gore to come...
