LEGO City: Deep Sea Adventure is the name of a new submarine ride now open at LEGOLAND California Resort.

The interactive attraction feature more than 2,000 sea animals including several species of sharks, rays and other tropical fish amid new LEGO models, all themed around a ship’s sunken treasure.

Deep Sea Adventure represents Merlin Entertainments’ largest single investment for a ride in any Legoland park and follows the introduction of similar attractions at other parks within the chain. For the first time in the United States, Legoland California Resort brings guests onboard a submarine ride vehicle where they’ll discover an amazing ‘undersea’ world.

Through the use of touchscreens at each porthole inside the sub, guests can help the Lego dive team identify Lego gems, pearls, gold coins and more throughout the more than four minute journey. Guests can reach one of three levels during each ride: Junior, Senior and Master Explorer.

Before guests board the yellow pound submarines, they are given a briefing on the mission that awaits them by a 3-feet-tall (1m) Lego diver whose face, with the help of a projector screen, is animated as he gives instructions to the explorers.

As guests exit the ride, they enter the retail space where they can build their own virtual fish from Lego and “release” it into the virtual ocean. If they’d like to build their own fish at home, all of the Lego elements are available for purchase.
