In the Dream World, imagination reigns supreme! The LEGO DREAMZzz Castle Nocturnia (71486) building set transforms pretend play into an epic adventure for kids 10 years old and up. This fantasy building toy brings the magic of the hit TV show to life through revolutionary dreamcrafting—where young builders can flex their creativity and decide how to finish the build! Kids can construct their dream fortress, then rotate sections to reveal hidden wonders: a secret cave, a majestic throne room, a cozy library, and a cascading waterfall. The innovative design allows dreamers to choose between two building modes, each featuring three sections: a fortified tower, a mighty castle, and an enchanted forest nest, providing multiple play options. Six minifigures, including Mateo, Izzie, Mrs. Castillo, their dark doppelgangers MadTeo and Dizzy, and the menacing Never Witch, stand by ready to star in thrilling fantasy adventures. A fierce manticore figure, four dreamling figures, and Sneak the nightmare minion complete the magical ensemble. Story-led building instructions with comic-style illustrations, along with the LEGO Builder app, will immerse kids in the action while encouraging creative exploration beyond the build. Perfect as a cool gift for boys and girls who love imaginative play and the LEGO DREAMZzz universe. Contains 1,742 pieces.
