Legoland California has celebrated its 10th anniversary, launching a new 4D attraction and announcing that it will build a new slide.

The Carlsbad-based theme park, owned by Merlin Entertainments, launched its new “Bob the Builder and the Rollercoaster” 4D attraction, a 10-minute film that uses computer-generated animation with special effects such as wind and mist, at its 10th anniversary celebrations.

The park also announced the addition of a fifth attraction to its Land of Adventure called Dune Raiders, an Egyptian-bazaar themed, 30ft-high, six-lane slide that will open in time for 4 July.
