I have a lot of good ideas for the fourth park. I would have it themed around animation, mainly DreamWorks and Illumination properties.
For the stuff from other Universal Parks, I would want versions of the Far, Far Away and Madagascar areas from Singapore. (I haven't gone to that park, but some of the rides there look awesome!)
The Far, Far, Away area would have all of the attractions from Singapore except for Shrek 4D.
I'm not too sure if Shrek 4D would be moved to this area, since it will close at Universal Hollywood for a Kung Fu Panda 4D show with updated technology. However, the Madagascar area would be not only based on the Singapore Madagascar area, but it would also have the Madagascar Mad Pursuit coaster from MotionGate Dubai's Madagascar area.
The next area that would be in this park would be Troll Village, based on the movie Trolls. This area would be reminiscent of Seuss Landing, since it would have kiddie rides as well as a dark ride based on the film.
i love DreamWorks' new Captain Underpants movie, and thought it would be awesome for a themed area. The area would be themed around the movie’s depiction of Piqua, Ohio. (Warning, under the spoiler tag are spoilers for the Captain Underpants movie. If you haven't watched it, do not click on the spoiler tag.)
The first ride, which would be a dark ride called Captain Underpants: The Origin Story. would be based on the movie, with a primary focus on George, Harold, and Captain Underpants/Mr. Krupp. (Melvin and Professor Poopypants would be absent from the ride due to them being the main characters of the second ride.)
The second ride I would do for this area is The Perilous Plot of Professor Poopypants. This ride would take the riders into Professor Poopypants' Turbo Toilet 2000 as he tries to rid Piqua, Ohio of laughter. The ride would be perfect as a simulator ride, since the inside of the Turbo Toilet kinda would be perfect to replicate as a simulator.
Should the ride use a virtual queue, the waiting area would be themed around the Invention Conventi0n from the film. In this area, riders can look at and interact with various inventions that Melvin created. I have no idea for a way that riders would be picked to ride should the ride use a virtual queue.
Once in the preshow area, the riders are greeted by Melvin and Professor Poopypants. Professor Poopypants then explains that he has sent the riders here to help him out with his latest plan: to rid the world of laughter, and then he reluctantly retells the story of his humiliation at the Nobel Prize ceremony after Melvin asks him to explain why he did that. After this, Professor Poopypants shows the riders a safety video which he narrates. The riders are then escorted to the simulator.
The simulator has a screen and an animatronic of Professor Poopypants, similar to how C3P-O is inside the Star Tours: The Adventures Continue simulator. The ride begins with Professor Poopypants starting up the Turbo Toilet 2000 and taking it through Piqua, Ohio, before approaching Jerome Horowitz Elementary School. What follows is an abridged version of the final battle of the Captain Underpants movie, but the ride ends with George and Harold’s laughter destroying the lightbulb on the Turbo Toilet 2000, which causes the Turbo Toilet to malfunction and bounce the riders around while Adam Lambert’s cover of Think plays. When the Turbo Toilet shuts down, the simulator goes dark and we hear Professor Poopypants apologize to the riders, claiming that he will try to defeat Captain Underpants, George, and Harold himself.
This area also has meet and greets with George, Harold, Captain Underpants, Professor Poopypants, and Melvin Sneedly. It also has a children’s play area based on George and Harold’s treehouse. There are two quick-service restaurants in the area: The Cafeteria and Professor P’s Ice Cream Truck (which isn’t actually a restaurant, but like Bumblebee Man’s taco truck in the Springfield area of Universal Studios. The store in this area is called Store-O-Rama, and on the inside, is decorated with pictures from George and Harold’s comics.
As for a Illumination-themed areas, I would possibly do a Despicable Me area similar to the Super Silly Fun Land area in Hollywood, but bigger and with more rides. I would also do a Sing area, which would consist of a show, a ride called Gunter's Dance Floor that's similar to Disneyland's Mater's Junkyard Jamboree, and a restaurant where you can dine with Sing characters.
I also find it shocking that Universal hasn't incorporated The Land Before Time into their theme parks, so I would put a Land Before Time area into the park.
