The LEGO DREAMZzz theme, based on the animated series, features Mateo, Izzie, Cooper, and their friends defending the dream world from the Nightmare King. The sets are unique because their building instructions are story-led, inviting children to create fantastical creatures and vehicles by choosing between different building paths.
