This could be accomplished by creating exclusive parks on the island that are underwater in a walled off area. This wall is indestructable and is made of concrete. This would be done with a manmade lake and would function similarly to how underwater attractions exist in real life in modern zoos. The paths would be replaced by underwater tunnels. The Gyrospheres would be replaced by the submarines you see in Jurassic World Fallen Kingdom. There would be two types of submarines, one for guests and one for park workers to replace the jeeps. There would be metal meshes that would separate the attractions from each other, each with a varying strength. Most of the buildings would be redesigned to connect with the underwater tunnels, there would be viewing outposts that resemble the viewing platforms. For the Ichthyosaur there could be an attraction where the guests could scuba dive and interact with the prehistoric dolphins. The parks would use underwater sounds as ambience and would have a blue hue to them. The game would function the same way as the regular game, except that the animals can rise or sink to the water (same way the helicopter does) Some of the attractions would have glass viewing where you can see the guests inside.
